When to Upgrade Your WRX or STI Lighting
Stock halogen headlights and tail lights on the 2015-2021 Subaru WRX and STI are functional but leave room for improvement in output, visibility, and appearance. Upgrading to LED units improves nighttime visibility and gives the car a cleaner, more modern look without modifying factory wiring.
Headlights vs Tail Lights: Where to Start
Most WRX and STI owners start with tail lights since the visual impact is immediate and installation is straightforward. Headlight upgrades like the OLM Hikari Series deliver more functional value with improved road illumination and a direct plug-and-play swap for stock halogens.
