These are the exact headlamps that come on the WRX STi. They're similar to the stock WRX lamps, but the low beam is a real High Intensity Discharge (HID) light. It burns brighter and whiter than traditional halogen filament bulbs.
Priced per pair. Kit includes two lamp housing with integral ballasts and igniters, plus leveling switch. Bolts directly in to any '04-05 Impreza or WRX, but there are some wiring modifictions required. The factory daytime running lamps must be disabled.
