Best Interior LED Lights for Subaru WRX (2026): Ambient & Dome Kits
WRX owners upgrading the cabin want one of two things: LED bulb replacements for the dim factory dome, map, and trunk lights, or a color-changing ambient kit for the footwells and dash. WRX dome and map lights commonly use 31mm festoon bulbs, with 194/T10 wedges in the trunk and plate. Here are the best plug-and-play bulbs and ambient RGB kits.

🧭 How to Choose the Best Interior LED Lights for Your Subaru WRX
Bulb replacement vs ambient kit
Bulb replacements swap the WRX's dome, map, and trunk bulbs for brighter white LEDs, plug-and-play. Ambient kits add color-changing strips or fiber and require routing wires. Choose based on whether you want cleaner factory light or a new custom color scheme.
Getting the right bulb size
Most WRX dome and map lights use a 31mm festoon bulb, while trunk and plate lights use a 194/T10 wedge. Pull one bulb to confirm before ordering, or buy a multi-size kit to cover every socket.
App/RGB control and install difficulty
RGB kits like Govee power easily from 12V or USB, but hiding strips under trim and running clean wire takes time. Keep all wiring clear of the dash and knee airbag areas. Bulb swaps are a ten-minute job.
❓ Frequently Asked Questions
What bulb size does the Subaru WRX dome light use?
Most WRX dome and map lights use a 31mm festoon bulb, while trunk and license plate lights use a 194/T10 wedge. Confirm by pulling a bulb before ordering.
Will LED interior bulbs cause errors on my WRX?
Interior lights are not typically monitored, so LED swaps rarely trigger any warning. A CANbus-friendly or vehicle-matched kit prevents flicker and keeps everything error-free.
Are ambient RGB kits hard to install in a WRX?
Placing the strips is easy, but hiding wires under trim and reaching a power source takes an hour or two. Route all wiring clear of airbag zones for a safe, clean install.
