Gen2 Housing Design

Our redesigned Gen2 4x6 housings are engineered specifically for LED bulbs, helping produce a cleaner, more controlled beam pattern with a defined cutoff for improved nighttime visibility and reduced unwanted glare.

The adjustable rotating bulb base allows the LED chips to be properly positioned inside the housing for precise beam alignment and optimal light output.

Unlike many lower-cost conversion kits that use plastic lenses, RMS Lighting housings feature real OE-style glass lenses that resist yellowing and hazing over time while maintaining the classic appearance of the original sealed beam headlights.
