2019 Subaru WRX Headlight Bulb Size
The 2019 model year proved the WRX could carry special-edition status — the Series.Gray limited edition brought exclusive paint, black accents, and premium trim details, while the STI received the track-focused S209 in an extremely limited production run. Improved infotainment rounded out the updates for the standard lineup. The 2019 Subaru WRX headlight bulb size is H11 for the low beams, 9005 for the high beams, and H16 for the fog lights. The base and Premium trims retain halogen reflector headlights, with factory LED units available on the Limited.
Whether you own the Series.Gray or a standard WRX, upgrading to 2019 Subaru WRX LED headlights delivers an instant visual improvement that matches the car's performance intent. The boxer engine rumble and aggressive stance deserve a front end that looks as sharp at night as it does during the day, and LED bulbs close that gap in under 30 minutes.
Choosing LED or HID for Your 2019 WRX
The 2019 WRX continues to use the VA-generation headlight housings that have been refined since 2015, and these housings pair well with aftermarket LED bulbs. An H11 LED kit replaces the factory halogen with a direct-fit bulb that locks into the same socket and uses the same wiring connector. Full 6000K output is available instantly — a meaningful advantage for a car that frequently gets driven to early-morning meets, late-night cruises, and weekend canyon sessions.
HID kits appeal to WRX owners who want the absolute maximum light on the road. The xenon arc creates a beam with more raw density than LED, which translates to better visibility at the extreme limits of the beam's reach. Each HID bulb connects to a ballast that tucks into the engine bay. Total installation time for both headlights and both fogs runs about an hour.
Every HID Nation kit ships free with a lifetime warranty. For a limited-edition car like the Series.Gray or S209, knowing your headlight kit is backed for life takes the stress out of modifying a rare vehicle.
Frequently Asked Questions
What headlight bulb does the 2019 Subaru WRX use?
The 2019 Subaru WRX uses H11 bulbs for the low beams, 9005 bulbs for the high beams, and H16 bulbs for the fog lights. This applies to the base WRX, Premium, and halogen-equipped trims. The Limited trim features factory LED low beams with an integrated module. The STI, including the S209, uses the same bulb sizes as the standard WRX on halogen trims.
Is the H16 fog light bulb compatible with H11 LED kits?
No, the H16 and H11 are not directly interchangeable even though they look similar. The H16 has a slightly different tab arrangement and lower factory wattage. The 2019 WRX uses H11 for headlights and H16 for fog lights, so you need to order the correct size for each position. HID Nation sells both H11 and H16 LED kits, making it easy to upgrade headlights and fogs together while keeping the correct fitment.
Will LED headlights look right on the 2019 WRX Series.Gray?
LED headlights are one of the best visual complements to the Series.Gray's exclusive cool-toned exterior color and dark accents. The 6000K white LED output pairs naturally with the gray paint and black wheels, creating a cohesive, purposeful look that enhances the limited-edition aesthetic. Many Series.Gray owners consider LED headlights a must-have modification because the factory halogen's warm yellow clashes with the car's cool-toned design language.
Do I need a CANBUS decoder for LED headlights on the 2019 WRX?
In the vast majority of cases, no. The 2019 WRX's electrical system does not use aggressive CANBUS monitoring on the headlight circuit. HID Nation's LED bulbs are designed to draw a wattage load similar to the factory halogen, so the car's computer does not flag a bulb-out warning. A small number of owners have reported minor flicker at startup, which is resolved with an inexpensive anti-flicker harness, but most installations are trouble-free right out of the box.
Can I upgrade just the fog lights to LED without changing the headlights?
You can, but we recommend upgrading both at the same time. Running LED fog lights in H16 alongside halogen H11 headlights will create a noticeable color difference — white fogs under yellow headlights looks mismatched. If budget is a concern, start with the H11 headlight LEDs first since they make the biggest visual impact, then add the H16 fog LEDs when you are ready for the complete front-end transformation.
