2020 Chevrolet Silverado 1500 Headlight Bulb Size
Building on the all-new T1XX platform introduced in 2019, the 2020 Chevrolet Silverado 1500 brought meaningful additions — most notably the 3.0L Duramax diesel option, the Multi-Flex tailgate on certain trims, and expanded standard features across the lineup. The 2020 Chevrolet Silverado 1500 headlight bulb size is H11 for the low beam and 9005 for the high beam. Like the 2019 model, fog light-equipped 2020 Silverados use H11 bulbs rather than the 5202 fog lights found on the older K2XX generation.
Halogen headlights remain standard on the WT and Custom trims, so there is a large population of 2020 Silverados that can benefit from a headlight upgrade. If you are looking for 2020 Chevrolet Silverado 1500 LED headlights, plug-and-play kits are readily available for every bulb position on this truck.
Upgrading the 2020 Silverado 1500 Headlights to LED or HID
The 2020 Silverado 1500 shares its headlight housing design with the 2019 model, so bulb access and installation remain identical. For the H11 low beam, reach behind the housing from the engine bay, twist out the halogen bulb, and twist in the LED replacement. The compact driver unit mounts nearby with a zip tie or bracket. Expect to finish both sides in roughly 20 minutes.
HID conversion kits offer a different approach — maximum raw output through a xenon arc bulb paired with a slim ballast. The beam is intensely bright and reaches farther than LED in some configurations, making HID popular among owners who tow heavy loads down dark highways. Installation takes about 40 minutes for both sides.
Since the 2020 Silverado uses H11 in both the headlight and fog light positions, upgrading all forward lighting is simpler than on the previous generation. Order H11 LED bulbs for the low beams and fog lights, 9005 for the high beams, and you have a complete set. HID Nation offers free shipping on every order, backed by a lifetime warranty on all kits.
Frequently Asked Questions
What headlight bulb size does a 2020 Chevrolet Silverado 1500 use?
The 2020 Chevrolet Silverado 1500 uses H11 for the low beam, 9005 for the high beam, and H11 for the fog lights. These sizes are the same as the 2019 Silverado 1500 on the T1XX platform. The fog light change from 5202 (used on 2014-2018 models) to H11 is an important distinction when ordering parts.
Does the 2020 Silverado Duramax diesel use different headlights?
No. The 2020 Silverado 1500 with the 3.0L Duramax diesel uses the same headlight bulb sizes as every other 2020 Silverado 1500 engine option — H11 low beam, 9005 high beam, and H11 fog lights. The engine choice does not affect the headlight fitment. LED and HID kits fit all 2020 Silverado 1500 configurations.
Are 2020 Silverado 1500 headlight bulbs the same as the 2019 model?
Yes. The 2019 and 2020 Silverado 1500 are both on the T1XX platform and share the same headlight bulb sizes — H11 low beam, 9005 high beam, and H11 fog lights. LED or HID kits purchased for one model year will fit the other. The headlight housing shapes are also the same between these two years.
What is the best complete lighting upgrade for a 2020 Silverado 1500?
For a full forward lighting overhaul on the 2020 Silverado 1500, upgrade all three positions: H11 LED low beams, 9005 LED high beams, and H11 LED fog lights. Because the low beam and fog light share the same H11 size, ordering is straightforward. This combination replaces every halogen bulb in the front of the truck and delivers a consistent, bright white output across all lighting modes.
Will LED headlights cause dashboard warning lights on a 2020 Silverado 1500?
Most quality LED conversion kits, including those from HID Nation, are designed with built-in CANbus compatibility to prevent dashboard error codes and bulb-out warnings on the 2020 Silverado 1500. If a warning does appear, an anti-flicker harness or load resistor resolves it. HID Nation customer support can help troubleshoot any compatibility questions before or after purchase.
