Whether you want better nighttime visibility or a head-turning show car, LEDs are the best place to start. Here are the top lighting upgrades for the 2015-2020 WRX and STi.

LED Fog Light Bulbs
H11-size SLF and SL1 LED fog light bulbs are direct drop-in upgrades for the WRX and STi's stock fog lights. The SLF delivers 780 lab-verified lumens with a precisely focused beam pattern — more usable light without glare. Available in 6000K cool white and 3000K selective yellow for that classic JDM look. The SL1 steps up to 1,630 lab-verified lumens for maximum brightness. Both install in under 20 minutes.
SAE/DOT LED Lightbar Kit
The SAE/DOT LED Lightbar Kit includes everything needed to mount a pair of 6" Stage Series Light Bars behind the factory bumper for a clean, low-profile rally-inspired look. CAD-designed brackets utilize factory mounting points for straightforward installation. Available in white or amber.
Tail as Turn® Module
The Tail as Turn® + Backup Module converts your WRX's tail lights to function as turn signals for a unique, modern look. With the original turn signal socket freed up, you can install additional backup LEDs for a major boost in rear-facing visibility. 100% plug-and-play.
SmartTap LED Flasher Relay
The SmartTap LED Flasher Relay is a direct replacement for the WRX's factory CF18 (LM449) flasher. It adds tap-turn functionality, programmable strobe hazards, arrival and departure lighting, and fixes hyperflashing when running LED turn signal bulbs. 100% plug-and-play.
C-Light DRL Switchback Boards
The C-Light DRL Switchback LED Boards upgrade the factory WRX C-light with a much brighter, more modern appearance. Computer-designed for perfect fitment. When paired with the DRL Harness, they illuminate in bright white as the DRL and flash amber with the factory turn signal for a unique switchback effect.
Interior LED Kit
The WRX Interior LED Kit includes everything needed to upgrade vanity lights, map lights, dome lights, trunk lights, and license plate lights to LED. Every bulb is completely plug-and-play for an instant cabin upgrade.
Fitment: All 2015-2020 Subaru WRX and STi models, all trim levels. All upgrades backed by a 3-year warranty.
