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.
