Headlight & Fog Light Bulb Cross-Reference Guide: Complete 2026 Chart
A headlight bulb cross-reference chart maps every automotive bulb number to its equivalents — because many bulbs carry different part numbers despite being physically identical. For example, H11, H8, and H9 are all the same base; 9005 and HB3 are the same bulb with different regional names. Use this guide by finding your current bulb number in any table below, then reading across to see every compatible replacement.
We built this chart from 25 years of selling and installing headlight bulbs. It covers 120+ bulb types across headlights, fog lights, turn signals, brake lights, interior lights, and HID systems — more than any other reference online.
Single-Beam Headlight Bulbs
Single-beam bulbs handle one function — either low beam or high beam, but not both. Most modern vehicles from 2000 onward use a single-beam low beam paired with a separate single-beam high beam. If your car uses H11 low beams, you probably have 9005 high beams (the most common single-beam pairing we sell at HID Nation).
| Bulb Number | Cross-Reference / Aliases | Wattage | Base Type | Typical Application | HID Nation |
|---|---|---|---|---|---|
| H1 | P14.5s, 64150 | 55W | P14.5s | Low beam, high beam, or fog light (older European vehicles) | H1 LED |
| H3 | 64151, 6336 | 55W | PK22s (wire terminal) | Fog lights, some older high beams | H3 LED |
| H7 | 64210, 12972 | 55W | PX26d | Low beam (common in European and Korean vehicles — VW, BMW, Audi, Hyundai, Kia) | H7 LED |
| H11 | H8, H9, H16 (Type A), 64211, 64212, 12362 | 55W (H11), 35W (H8), 65W (H9) | PGJ19-2 (H11), PGJ19-1 (H8), PGJ19-5 (H9) | Low beam, fog light — the most popular single-beam headlight bulb in North America | H11 LED |
| H11B | (no common aliases — unique base) | 55W | PGJY19-2 (protruding prongs) | Low beam in select Kia, Hyundai models (2006-2015 era) | H11B LED |
| 9005 | HB3, H10, 9040, 9045, 9055, 9140, 9145, 9150, 9155 | 60W / 65W | P20d | High beam (most common), some fog lights (as 9145/H10) | 9005 LED |
| 9006 | HB4, 9006XS | 51W / 55W | P22d | Low beam (vehicles from mid-1990s to mid-2000s) | 9006 LED |
| 9012 | HIR2 | 55W | PX22d (similar to 9006) | Low beam (Toyota, Scion, Dodge, some GM vehicles). Higher-efficiency variant of 9006 with IR-reflective coating | 9012 LED |
| 880 | H27W/1, 899 | 27W | PG13 | Fog lights | 880 LED |
| 881 | H27W/2, 886, 894, 896, 898 | 27W | PGJ13 | Fog lights | 881 LED |
| 5202 | PS24W, 12086, 9009, 2504, PSX24W*, H16 (Type B) | 24W | PG20/3 | Fog lights (GM trucks, Jeep Wrangler, Dodge, Chrysler) | 5202 LED |
*Note on PSX24W: While 5202 and PSX24W are frequently listed as interchangeable, the PSX24W (used in some Subaru, Jeep, and Chrysler models) has slightly different pin spacing from the PS24W/5202. The bases are close but not a guaranteed direct fit without a minor tab adjustment. We cover this in the edge cases section.
Dual-Beam Headlight Bulbs
Dual-beam (or bi-beam) bulbs combine both low and high beam in a single bulb. You can tell you have a dual-beam setup if your vehicle has only one bulb per headlight assembly, and it switches between low and high beam. These are increasingly less common in newer vehicles but still widespread in trucks, Jeeps, and budget vehicles.
| Bulb Number | Cross-Reference / Aliases | Wattage | Base Type | Typical Application | HID Nation |
|---|---|---|---|---|---|
| H4 | 9003, HB2, 64193, 12342, HS1 | 60W high / 55W low | P43t-38 | Headlight (Jeep Wrangler JK, Toyota Tacoma pre-2016, older Honda Civic, many motorcycles) | H4 LED |
| H13 | 9008 | 60W high / 55W low | P26.4t | Headlight (Ford F-150 2004-2014, Dodge Ram 2006-2012, Jeep Wrangler JL) | H13 LED |
| 9004 | HB1 | 65W high / 45W low | P29t | Headlight (older vehicles — Jeep Cherokee XJ, Ford Ranger pre-2001, Honda Prelude) | 9004 LED |
| 9007 | HB5 | 65W high / 55W low | PX29t | Headlight (Ford F-150 1997-2003, Nissan Frontier, Dodge Caravan, Ford Taurus) | 9007 LED |
All four dual-beam types are available as LED headlight bulb upgrades from us. Our dual-beam LEDs replicate the hi/lo switching mechanism, so your high beam flash and auto-dimming features continue to work normally.
D-Series HID / Xenon Bulbs
D-series bulbs are factory-installed HID (High Intensity Discharge) bulbs found in OEM xenon headlight systems. They produce light through an arc discharge rather than a filament. We have been working with these bulbs since the late 1990s when they first appeared in luxury vehicles, and one of the most common mistakes we see is people mixing up voltage groups.
| Bulb Number | Cross-Reference / Aliases | Wattage | Voltage (Igniter) | Base Type | Key Notes | HID Nation |
|---|---|---|---|---|---|---|
| D1S | D1C, 66140, 85415 | 35W | 85V AC | PK32d-2 (igniter integrated) | For projector housings. Igniter built into base. Contains mercury. | D1S HID |
| D1R | 66150, 85409 | 35W | 85V AC | PK32d-3 (igniter integrated) | For reflector housings. Opaque shield coating. Contains mercury. | D1R HID |
| D2S | D2C, 66240, 85122 | 35W | 85V AC | P32d-2 (external igniter) | For projector housings. External igniter/starter. Contains mercury. | D2S HID |
| D2R | 66250, 85126 | 35W | 85V AC | P32d-3 (external igniter) | For reflector housings. Opaque shield coating. Contains mercury. | D2R HID |
| D3S | D3C, 66340, 42302 | 35W | 42V AC | PK32d-5 (igniter integrated) | For projector housings. Mercury-free. Same form factor as D1S but different voltage. | D3S HID |
| D3R | 66350, 42306 | 35W | 42V AC | PK32d-6 (igniter integrated) | For reflector housings. Mercury-free. Rare — very few vehicles use D3R. | Contact us |
| D4S | D4C, 66440, 42402 | 35W | 42V AC | P32d-5 (external igniter) | For projector housings. Mercury-free. Same form factor as D2S but different voltage. Common in Toyota/Lexus. | D4S HID |
| D4R | 66450, 42406 | 35W | 42V AC | P32d-6 (external igniter) | For reflector housings. Mercury-free. Used in some Toyota/Lexus models. | D4R HID |
| D5S | 66548, 12410 | 25W | 12V DC | PK32d-7 (integrated igniter + ballast function) | Unique — runs on 12V DC. No external igniter required. Mercury-free. Lower output than D1S-D4S. Used in select VW, Audi models (2013+). | Contact us |
| D8S | 66548 (varies by manufacturer) | 25W | 42V AC | PK32d-1 (built-in igniter) | Mercury-free. 25W. Shares 42V platform with D3S/D4S but lower wattage. Found in select newer European vehicles. | Contact us |
The quick rule for D-series: D1 and D2 are the older, 85V, mercury-containing generation. D3 and D4 are the newer, 42V, mercury-free generation. Within each generation, the difference between "1" and "2" (or "3" and "4") is whether the igniter is integrated (D1/D3) or external (D2/D4). "S" means projector, "R" means reflector. D5S and D8S are specialty low-wattage variants. For a deep-dive comparison, read our D1S vs D2S vs D3S vs D4S guide.
Fog Light Bulbs
Fog light bulb sizing is where most of the confusion happens. The 880/881 family alone has ten-plus part numbers that all share a base style, and the 5202/PSX24W family has at least six aliases. We get calls about this every week. Here is the full breakdown.
880/881 Fog Light Family
| Bulb Number | Cross-Reference / Aliases | Wattage | Base Type | Typical Application | HID Nation |
|---|---|---|---|---|---|
| 880 | H27W/1, 899, 862 | 27W | PG13 | Fog lights (GM vehicles, older Hyundai/Kia) | 880 LED |
| 881 | H27W/2, 886, 889, 894, 896, 898 | 27W | PGJ13 | Fog lights | 881 LED |
| 885 | (881 family) | 50W | PGJ13 | Fog lights (higher wattage variant) | 881 LED |
| 886 | 881, 889 | 50W | PGJ13 | Fog lights | 881 LED |
| 889 | 881, 886 | 27W | PGJ13 | Fog lights | 881 LED |
| 893 | 880, 899 | 37.5W | PG13 | Fog lights | 880 LED |
| 894 | 881, 896, 898 | 37.5W | PGJ13 | Fog lights | 881 LED |
| 896 | 881, 894, 898 | 37.5W | PGJ13 | Fog lights | 881 LED |
| 898 | 881, 894, 896 | 42W | PGJ13 | Fog lights | 881 LED |
| 899 | 880, 893, 862 | 37.5W | PG13 | Fog lights | 880 LED |
| 862 | 880, 899 | 27W | PG13 | Fog lights | 880 LED |
| 890 | 892, 880 family | 27W | PG13 | Fog lights | 880 LED |
| 891 | 881 family | 27W | PGJ13 | Fog lights | 881 LED |
| 892 | 890, 880 family | 27W | PG13 | Fog lights | 880 LED |
The key distinction in this family: 880-style bulbs (880, 890, 892, 893, 899, 862) use a PG13 base with a straight indexing tab. 881-style bulbs (881, 885, 886, 889, 891, 894, 896, 898) use a PGJ13 base with an angled indexing tab. Within each group, the bulbs are fully interchangeable — only the wattage of the original halogen differs, and LED replacements eliminate wattage concerns entirely.
Other Fog Light Bulbs
| Bulb Number | Cross-Reference / Aliases | Wattage | Base Type | Typical Application | HID Nation |
|---|---|---|---|---|---|
| H10 | 9145, 9140, 9155, 9150, 9040, 9045, 9055 (all = 9005 base) | 42W / 45W | PY20d (same as 9005) | Fog lights (Dodge Ram, Ford F-150, Chevy Silverado pre-2014) | 9005/H10 LED |
| H16 (Type A) | H11, H8, 64219 (L-shaped, PGJ19 base) | 19W | PGJ19-3 | Fog lights (Toyota, Honda, Subaru — Japanese-market standard) | H11 LED |
| H16 (Type B) | 5202, 2504, PS24W, PSX24W*, 9009, 5201, 12086 (T-shaped) | 19W / 24W | PG20/3 | Fog lights (Chevy, Dodge, Ford, GMC, Jeep — US-market) | 5202 LED |
| PSX24W | 2504, 12276 (similar to PS24W/5202 but different pin offset*) | 24W | PG20/7 | Fog lights (Subaru Impreza/Crosstrek, Jeep Patriot/Compass, Chrysler 200) | PSX24W LED |
| PSX26W | 12278 | 26W | PG18.5d-3 | Fog lights (select Subaru Legacy/Outback) | Contact us |
| H3 | (see single-beam section) | 55W | PK22s | Fog lights on older vehicles | H3 LED |
Sealed Beam Headlights
Sealed beam headlights are the old-school units where the entire headlight is one sealed glass assembly — lens, reflector, and filament all fused together. If your vehicle was made before the mid-1980s (or is a Jeep Wrangler YJ/TJ, classic truck, or commercial vehicle), you likely have sealed beams. We sell LED sealed beam replacements that drop directly into the original housing.
| Bulb Number | Cross-Reference / Aliases | Wattage | Shape / Size | Typical Application | HID Nation |
|---|---|---|---|---|---|
| H6054 | 6054, H6054LL | 60W/55W (dual beam) | 7" x 6" (200mm x 142mm) rectangular | Jeep Wrangler YJ, Cherokee XJ, Ford trucks pre-1997, Toyota pickup | 7x6 LED |
| H6024 | 6024, H6024LL, PAR56 | 60W/40W (dual beam) | 7" round (178mm) | Jeep Wrangler CJ/TJ, classic Mustang, VW Beetle, Land Rover Defender | 7" Round LED |
| H4651 | 4651 | 50W (high beam only) | 7" x 6" rectangular (high beam) | 4-headlight rectangular systems — high beam unit | 7x6 LED |
| H4656 | 4656 | 35W (low beam only) | 7" x 6" rectangular (low beam) | 4-headlight rectangular systems — low beam unit | 7x6 LED |
| H5001 | 5001 | 37.5W (high beam only) | 5-3/4" round (146mm) — high beam | 4-headlight round systems — high beam unit | 5.75" Round LED |
| H5006 | 5006 | 35W (low beam only) | 5-3/4" round (146mm) — low beam | 4-headlight round systems — low beam unit | 5.75" Round LED |
| H4666 | 4666 | 37.5W (low beam) | 4" x 6.5" rectangular (100mm x 165mm) | 4-headlight smaller rectangular systems | LED Sealed Beam |
| H6545 | 6545 | 65W/45W (dual beam) | 5-3/4" round (dual beam) | Dual-beam 5-3/4" round systems | 5.75" Round LED |
Turn Signal Bulbs
Turn signal bulbs come in three base families: bayonet (1156/1157 series), wedge (3156/3157 and 7440/7443 series), and a few specialty types. The naming confusion here is mainly US-vs-European designations — for example, 1156, 7506, and P21W are the exact same bulb with three different names.
| Bulb Number | Cross-Reference / Aliases | Wattage | Base Type | Typical Application | HID Nation |
|---|---|---|---|---|---|
| 1156 | 7506, P21W, BA15s, 1141, 1073, 1003, 93, 97, 631 | 26.9W | BA15s (single contact bayonet) | Front/rear turn signal, reverse light, single-function tail light | 1156 LED |
| 1157 | 7528, P21/5W, BAY15d, 2057, 2357, 1034, 1154, 1016, 7225 | 26.9W / 8.3W | BAY15d (dual contact bayonet) | Brake/tail combo, dual-function turn signal | 1157 LED |
| 3156 | 3456, 4156, P27W | 26.9W | W2.5x16d (plastic wedge) | Turn signal, reverse light (GM vehicles especially) | 3156 LED |
| 3157 | 3357, 3457, 4157, P27/7W, 3057 | 26.9W / 8.3W | W2.5x16q (plastic wedge, dual filament) | Brake/tail/turn combo (common in GM, Ford, Chrysler) | 3157 LED |
| 7440 | W21W, 992, 7441, T20 | 21W | W3x16d (wedge) | Turn signal, reverse light (common in Japanese vehicles) | 7440 LED |
| 7443 | W21/5W, 7444, T20 | 21W / 5W | W3x16q (wedge, dual filament) | Brake/tail/turn combo (Honda, Toyota, Nissan, Subaru) | 7443 LED |
| 7506 | 1156, P21W, BA15s | 21W | BA15s | European designation for 1156 — same exact bulb | 1156 LED |
| 7507 | PY21W, BAU15s, 12496 | 21W | BAU15s (offset pins — amber glass) | Amber front turn signal (European vehicles — BMW, VW, Mercedes) | 7507 LED |
Single vs. dual filament rule: A single-filament bulb (1156, 3156, 7440) can physically fit into a dual-filament socket (1157, 3157, 7443), but not vice versa. The single-filament bulb will work for one function but leave the second function dead. If you are replacing a dual-filament bulb, always use the correct dual-filament replacement.
Brake & Tail Light Bulbs
Most brake and tail lights use the same bulb families as turn signals (1157, 3157, 7443 for dual-filament applications). Below are the common bulbs and some additional specialty types we see in brake and tail light positions.
| Bulb Number | Cross-Reference / Aliases | Wattage | Base Type | Typical Application | HID Nation |
|---|---|---|---|---|---|
| 1157 | 2057, 2357, 7528, P21/5W, BAY15d | 26.9W / 8.3W | BAY15d | Brake light (bright) + tail light (dim) combo | 1157 LED |
| 3157 | 3357, 3457, 4157, 3057 | 26.9W / 8.3W | W2.5x16q | Brake/tail combo (Ford, GM, Chrysler) | 3157 LED |
| 7443 | W21/5W, 7444 | 21W / 5W | W3x16q | Brake/tail combo (Honda, Toyota, Nissan) | 7443 LED |
| 2835 | (LED chip type — not a halogen cross-ref) | Varies | Varies | Common LED chip used in replacement bulbs — often confused with bulb number 2825 | — |
| 921 | 912, W16W, 906, 904, 916, 917, 918, 920, 922 | 17.9W (921) / 12.8W (912) | W2.1x9.5d (wedge) | Reverse (backup) light, third brake light (CHMSL) | 921 LED |
| 7440 | W21W, 992 | 21W | W3x16d | Reverse light, single-function tail (some vehicles) | 7440 LED |
| 1156 | 7506, P21W, 1141 | 26.9W | BA15s | Reverse light, single-function brake or tail | 1156 LED |
If you are upgrading to LED brake lights, we strongly recommend choosing bulbs with a built-in CANBUS decoder or adding an external resistor. Many modern vehicles will throw a "bulb out" warning with LED replacements because LEDs draw far less power than halogens, and the vehicle's computer interprets the low draw as a burned-out bulb.
Interior, Map & Dome Bulbs
Interior bulbs are small, low-wattage, and come in wedge or festoon (tube) styles. The good news is that LED replacements for interior bulbs are straightforward — they produce much brighter, whiter light without the heat of incandescent bulbs, and they last essentially forever in low-duty-cycle interior applications.
| Bulb Number | Cross-Reference / Aliases | Wattage | Base Type | Typical Application | HID Nation |
|---|---|---|---|---|---|
| 194 | 168, T10, W5W, 2825, 147, 152, 158, 159, 161, 175, 184, 192, 193, 259 | 3.8W (194) / 4.9W (168) | W2.1x9.5d (T10 wedge) | Map lights, dome lights, side markers, license plate lights, instrument panel | 194 LED |
| 168 | 194, T10, W5W, 2825 | 4.9W | W2.1x9.5d (T10 wedge) | Same as 194 — slightly higher wattage halogen, identical base and LED replacement | 194 LED |
| 2825 | 194, 168, W5W, T10 | 5W | W2.1x9.5d | European designation for the 194/168 wedge. Same bulb. | 194 LED |
| 921 | 912, W16W, 906, 904, 916, 920, 922 | 17.9W | W2.1x9.5d (larger T15 wedge) | Interior dome, reverse lights, cargo area light | 921 LED |
| 912 | 921, W16W | 12.8W | W2.1x9.5d (T15 wedge) | Lower-wattage version of 921. Same base — LED replacement is universal. | 921 LED |
| 578 | 6411, 6413, 6418, 211-2, 212-2, C6W | 10W | SV8.5-8 (festoon, 41-42mm) | Dome light, map light, trunk light | 578 LED |
| 211-2 | 212-2, 214-2, 578, C5W | 12.4W | SV8.5-8 (festoon, 42mm) | Dome light, courtesy light — interchangeable with 578 in most applications | 578 LED |
| 212-2 | 211-2, 578, 214-2 | 12W | SV8.5-8 (festoon, 42mm) | Dome light, courtesy light | 578 LED |
| DE3175 | 3175, 6428, C5W (31mm) | 5W | SV7-8 (festoon, 31mm) | Map light, dome light (shorter festoon) | DE3175 LED |
| DE3022 | 3022, 6411 (31mm variant) | 5W | SV7-8 (festoon, 31mm) | Map light (very similar to DE3175) | DE3175 LED |
| 36mm festoon | 6418, 6461, C5W (36mm), DE3423 | 5W-10W | SV8.5 (festoon, 36mm) | Dome light, vanity mirror, some European vehicles | 36mm LED |
| 39mm festoon | 6411, 6423, C5W/C10W (39mm) | 10W | SV8.5 (festoon, 39mm) | Dome light, trunk light | 39mm LED |
| BA9s | 53, 57, 182, 257, T4W, 64111 | 4W | BA9s (miniature bayonet) | Interior lights, instrument cluster (older European vehicles) | BA9s LED |
Festoon length matters. Festoon (tube-shaped) bulbs come in 31mm, 36mm, 39mm, and 42mm lengths. A 31mm LED will rattle around in a 42mm socket and may not make electrical contact. Always measure your current festoon bulb or check the part number before ordering.
License Plate & Side Marker Bulbs
License plate and side marker positions almost always use one of the bulb types already covered in the interior section. Here is a quick reference for the most common fitments.
| Bulb Number | Cross-Reference / Aliases | Wattage | Base Type | Typical Application | HID Nation |
|---|---|---|---|---|---|
| 194 | 168, T10, W5W, 2825 | 3.8W | T10 wedge | License plate light (most common), front side markers | 194 LED |
| 2825 | 194, 168, W5W | 5W | T10 wedge | License plate (European name for 194/168) | 194 LED |
| DE3175 | 3175, 6428, C5W (31mm) | 5W | Festoon 31mm | License plate light (Honda, Acura, Toyota, Ford) | DE3175 LED |
| 578 | 211-2, 212-2, 6411 | 10W | Festoon 42mm | License plate light (trucks, SUVs), cargo light | 578 LED |
| PC194 | PC168, T10 (painted) | 3.8W | T10 wedge (amber or blue coated glass) | Instrument cluster, side marker (colored) | — |
| 74 | 37, 73, 79, T5 | 1.4W | T5 wedge (sub-miniature) | Instrument cluster, HVAC panel lights | — |
| 2057 | 1157, BAY15d | 26.9W / 6.7W | BAY15d | Side marker / parking light (dual filament, lower secondary wattage than 1157) | 1157 LED |
Confusing Edge Cases Explained
After 25 years of selling headlight bulbs, these are the compatibility questions that trip people up the most. We have seen every one of these mistakes — and some of them result in damaged ballasts, blown fuses, or bulbs that physically will not lock into the housing. Bookmark this section.
H11 vs. H11B — NOT the Same Bulb
The H11 and H11B look almost identical, but they have different base prong orientations. The H11 has prongs that are recessed (nested) inside the plug housing. The H11B has prongs that protrude outward. The headlight assemblies for each are designed differently, so an H11 physically cannot seat and lock into an H11B socket.
Who uses H11B? Select Kia Optima (2006-2015), Kia Forte, Hyundai Sonata, and Hyundai Elantra models. If you have one of these and cannot figure out why your new H11 bulb does not fit, you almost certainly need an H11B.
H16 Type A vs. H16 Type B — Completely Different Bulbs
This is one of the worst naming disasters in automotive lighting. "H16" refers to two completely unrelated bulbs depending on the market:
- H16 Type A (Japanese/ECE market): An L-shaped bulb with a PGJ19 base — essentially a lower-wattage H11 (19W vs 55W). Used as a fog light in Toyota Corolla, Honda Civic, Subaru WRX/Impreza, and many other Japanese-market vehicles. An H11 LED replaces it directly.
- H16 Type B (US/SAE market): A T-shaped bulb equivalent to 5202/2504/PS24W. Used as a fog light in Chevy Silverado, GMC Sierra, Dodge Charger, Jeep Wrangler JK. A 5202 LED replaces it.
These two bulbs share absolutely nothing except the name. Always verify which one your vehicle uses.
The 880/881 Fog Light Family — Which Are Truly Interchangeable?
The numbers 880, 881, 885, 886, 889, 890, 891, 892, 893, 894, 896, 898, 899, and 862 all belong to one extended family but split into two sub-groups based on indexing tab angle:
- 880 group (PG13, straight tab): 880, 862, 890, 892, 893, 899
- 881 group (PGJ13, angled tab): 881, 885, 886, 889, 891, 894, 896, 898
Within each group, every bulb is physically interchangeable. The only difference is the halogen wattage — 885 and 886 are 50W, while 880 and 881 are 27W — but this only matters for halogen. LED replacements are universally compatible within each group and typically fit both groups with a simple quarter-turn adjustment. In our experience, most LED 880/881 bulbs ship with a universal tab design that fits all 14 numbers.
D-Series Voltage Groups — Swapping WILL Damage Your Ballast
The four main D-series bulbs look nearly identical in pairs:
- D1S and D3S both have the igniter integrated into the base. Same physical shape. But D1S runs at 85V AC and D3S runs at 42V AC.
- D2S and D4S both use an external igniter. Same physical shape. But D2S runs at 85V AC and D4S runs at 42V AC.
- D5S is unique — 12V DC, no external igniter or ballast, 25W. Cannot be swapped with any other D-series.
- D8S uses 42V AC at 25W with a built-in igniter. Different base from D3S despite sharing the 42V platform.
Plugging a D2S (85V) into a D4S (42V) ballast means the ballast is delivering less than half the voltage the bulb needs. It either will not fire at all, or it will fire erratically and overstress the ballast trying to compensate. Going the other direction — D4S into a D2S ballast — hits the bulb with double its rated voltage, which can blow the bulb instantly and potentially damage the ballast. For detailed comparisons, see our HID bulb comparison guide.
9005 = HB3 (Same Bulb, Different Name)
9005 is the ANSI (American National Standards Institute) part number. HB3 is the ECE (Economic Commission for Europe) designation. They are the same bulb — same P20d base, same dimensions, same everything. If a European parts catalog calls for HB3, order a 9005. If your vehicle spec sheet says 9005, an HB3 from a European brand is identical. The same applies to 9145, H10, 9040, 9055, 9140, 9150, and 9155 — all the same physical base. Read our H11 vs 9005 comparison if you are unsure which of these your vehicle actually needs.
9006 = HB4 (Same Bulb, Different Name)
Same situation as above. 9006 = ANSI. HB4 = ECE. Identical bulb with a P22d base. See our 9005 vs 9006 comparison for a detailed breakdown of when each is used. The 9012 (HIR2) shares a very similar base and is sometimes listed as a cross-reference — while LED replacements often fit both, the OEM halogen bulbs are not identical due to the 9012's infrared-reflective coating.
H4 = 9003 = HB2 (Three Names, One Bulb)
H4 is the international/ECE name. 9003 is the ANSI name. HB2 is an alternate ECE code. All three are the same dual-beam bulb with a P43t base, delivering 60W on high beam and 55W on low beam. HS1 is also sometimes listed — it is a slightly lower-wattage variant (35/35W) used in motorcycles, but it shares the same P43t base and an LED H4 replacement works for all of them.
H13 = 9008 (Same Bulb)
H13 and 9008 are the same dual-beam bulb with a P26.4t base. This bulb was introduced by Ford in the early 2000s and became common in Ford F-150 (2004-2014), Dodge Ram (2006-2012), and Jeep Wrangler (2007+). Our H13 LED fits all 9008 applications.
1156 = 7506 = P21W (US vs. European vs. Metric Naming)
This is a naming-convention difference, not a compatibility difference:
- 1156 — ANSI trade number (used in the US)
- 7506 — Osram/Sylvania catalog number (used in Europe)
- P21W — IEC metric designation (21 watts, wedge base)
- BA15s — base type designation
All four names refer to the same single-contact bayonet bulb. The same applies to the dual-contact version: 1157 = 7528 = P21/5W = BAY15d. When you see any of these on a European vehicle's spec sheet (BMW, VW, Mercedes), just match it to the ANSI number and order accordingly.
PS24W vs. PSX24W — Close But Not Identical
The PS24W (commonly sold as 5202) and PSX24W (commonly sold as 2504) look very similar and are frequently listed as cross-references. They share the same general base shape and locking tab style. However, the wiring pins are inversed — meaning the positive and negative contacts are flipped. In practice, LED replacements are often non-polarity-sensitive and work in both sockets, but halogen PS24W and PSX24W bulbs should not be freely swapped. If your vehicle calls for PSX24W specifically (common in Subaru Crosstrek, Jeep Compass, Chrysler 200), order the PSX24W rather than assuming a 5202 will work.
How to Find Your Bulb Size
If you are not sure which bulb your vehicle uses, here are three reliable methods we recommend — in order of convenience.
Method 1: Use HID Nation's Vehicle Pages
The fastest way. Go to our vehicle bulb finder, select your year, make, and model, and we will show you every bulb size your vehicle uses — headlights, fog lights, turn signals, and interior lights. We have data for thousands of vehicles from 1990 to 2026.
Method 2: Check Your Owner's Manual
Your owner's manual has a "bulb specification" or "replacement bulbs" chart in the maintenance section (usually near the back). It lists every bulb position and the corresponding part number. This is the manufacturer's official specification and is always accurate.
Method 3: Remove and Read the Current Bulb
Open the headlight housing (usually accessible from behind the headlight assembly under the hood), remove the bulb, and read the part number printed or stamped on the base. Headlight bulbs (H11, 9005, H7, etc.) always have the number on the plastic base. Interior and signal bulbs may require a magnifying glass — the number is sometimes very small.
If all else fails, contact us directly. Give us your year, make, model, and trim level, and we will look it up for you. We do this dozens of times per day.
Frequently Asked Questions
Are H11 and H8 bulbs interchangeable?
Yes. H11, H8, and H9 share the same PGJ19 base and locking tabs. The difference is wattage: H11 = 55W, H8 = 35W, H9 = 65W. Any LED replacement for this family uses a universal design that fits all three sockets. See our H11 vs H9 vs H8 comparison for details on lumen differences between the halogen versions.
Is 9005 the same as HB3?
Yes. 9005 (ANSI) and HB3 (ECE) are the same bulb. Same P20d base, same wattage, same dimensions. The naming difference comes from US vs. European standards organizations. HB3 will work anywhere that calls for 9005, and vice versa.
Is 9006 the same as HB4?
Yes. 9006 = HB4. ANSI vs. ECE designation for the same P22d-base bulb.
What is the difference between H11 and H11B?
They are NOT interchangeable. The H11 has recessed prongs while the H11B has protruding prongs. The headlight assemblies are physically different. H11B is used in select Kia and Hyundai models (2006-2015). Always confirm which version your vehicle requires before ordering.
Can I swap D2S and D4S HID bulbs?
No. D2S operates on an 85V igniter/ballast, while D4S uses a 42V system. Mismatching the voltage will damage the ballast and likely destroy the bulb. They look nearly identical but are electrically incompatible. D2S also contains mercury; D4S does not.
What bulbs are interchangeable with 880?
The 880 is directly interchangeable with 862, 890, 892, 893, and 899 (all PG13 base, straight tab). It is closely related to the 881 group (881, 885, 886, 889, 891, 894, 896, 898) which uses an angled tab. LED replacements typically fit both groups.
Is H4 the same as 9003?
Yes. H4, 9003, and HB2 are all the same dual-beam halogen bulb with a P43t base. H4 is the international name, 9003 is the American name, and HB2 is an alternate European code.
What is the difference between 1156 and 1157?
The 1156 has a single filament (one function — turn signal OR reverse). The 1157 has dual filaments (two functions — brake AND tail, or turn AND marker). They use the same bayonet base diameter but 1157 has an extra contact point for the second filament. They are not interchangeable.
Are 7440 and 7443 interchangeable?
Partially. A 7440 (single filament) can fit into a 7443 socket, but it will only power one function. A 7443 cannot replace a 7440 in every application because the second filament contact may cause fitment issues. If your vehicle uses 7443, always use 7443.
What is the H16 fog light bulb equivalent?
It depends on which H16 your vehicle uses. H16 Type A (L-shaped, used in Japanese cars) = H11. H16 Type B (T-shaped, used in American cars) = 5202/2504. These are completely different bulbs that share the same name. Check your vehicle's market and model to determine which one you need.
How do I know if my headlight is single-beam or dual-beam?
If your vehicle has one bulb per headlight assembly that handles both low and high beams, it is dual-beam (H4, H13, 9004, or 9007). If it has two separate bulbs per assembly — one for low beam and one for high beam — it is single-beam (most commonly H11 low / 9005 high, or H7 low / 9005 high).
What does the "S" and "R" mean in D-series HID bulbs?
"S" stands for Shield and is designed for projector-style headlights. "R" stands for Reflector and has an opaque coating to create a proper beam cutoff in reflector-style headlights. Using a D1S in a D1R housing (or vice versa) causes incorrect beam patterns and potentially dangerous glare for oncoming traffic.
Will LED headlight bulbs fit my halogen headlight housing?
LED replacement bulbs are designed to match the exact base type and dimensions of the halogen bulb they replace. An H11 LED fits an H11 halogen socket. A 9005 LED fits a 9005 socket. No rewiring or housing modifications are needed. Browse our full LED headlight collection to find your size.
Can I use a higher-wattage halogen bulb in my headlight?
We do not recommend it. Using a higher-wattage halogen bulb (for example, putting an H9 at 65W in an H11 socket rated for 55W) increases heat output beyond what the housing, wiring harness, and connector are designed to handle. Over time this can melt the connector or damage the headlight lens. If you want more light, upgrade to LED — our LED bulbs produce 2-3x more light than halogen while drawing less power and producing less heat.
What is the difference between a D5S and other D-series HID bulbs?
The D5S is a 25W bulb that runs on 12V DC — it does not require an external igniter or traditional HID ballast. All other D-series bulbs (D1S, D2S, D3S, D4S) run at either 85V AC or 42V AC and require external ballasts. The D5S was designed for specific VW and Audi applications and cannot be swapped with any other D-series type.
