OLM Hikari Series LED Headlights for WRX and STI
The OLM Hikari Series is a direct replacement for the factory halogen headlights on the 2015-2021 Subaru WRX and STI. Output is significantly improved over stock with a cleaner, more modern light projection. No retrofitting, ballast, or additional hardware is required.
What to Expect From a Headlight Upgrade
Factory halogens on the WRX and STI deliver adequate output for everyday driving but fall short in low-visibility conditions. The OLM Hikari upgrade improves road illumination and gives the front end a cleaner look that complements both stock and modified builds.
Pair With Exterior Upgrades
Many WRX and STI owners combine headlight upgrades with exterior styling mods for a more complete front end transformation. Browse compatible bolt-on exterior parts on our WRX and STI exterior parts page or explore the full OLM lineup on our OLM brand page.
