Gen2 Housing Design
Our redesigned Gen2 4x6 headlight housings are engineered specifically for LED bulbs , helping produce a cleaner, more controlled beam pattern with a defined cutoff line.
The result is improved nighttime visibility while preserving the classic OEM appearance of your vehicle.
Unlike many lower-cost conversion kits that use plastic lenses, RMS Lighting housings feature real glass lenses that will not yellow over time . Our housings also utilize the proper LHD lens pattern , rather than RHD optics designed for vehicles driven on the opposite side of the road.
