AlphaRex PRO-Series Halogen Projector Headlights – Black | 2003–2009 4Runner
Update your fourth-generation 4Runner’s front end with AlphaRex PRO-Series halogen projector headlights in Black. The design pairs separate low- and high-beam H7 halogen projectors with white LED daytime running lights and sequential amber turn signals. These headlights fit 2006–2009 models directly; 2003–2005 models need the matching filler-panel and converter configuration.
