Keep the Original Look – Get Modern LED Performance

The RMS Lighting Gen1 kit is designed for enthusiasts who want better lighting without changing the classic appearance of their vehicle.

The OE-style glass lenses maintain the traditional sealed beam look, while the high-output H4 LED bulbs provide substantially improved nighttime visibility compared with traditional sealed beam headlights.

The adjustable rotating bulb base allows proper LED positioning and beam alignment for optimal light output.

Real Glass Lenses – Not Plastic

Unlike many lower-cost conversion kits that use plastic headlight housings, RMS Lighting Gen1 housings feature real glass lenses with durable metal backs.

Glass provides the classic appearance these vehicles were originally designed around while eliminating one of the biggest drawbacks of plastic replacement headlights:

Glass lenses will not yellow or haze like plastic lenses over time.

True Plug & Play Installation

Everything needed for the conversion is included.

The supplied harness adapters allow the 3-prong H4 LED bulbs to connect to factory 2-prong high beam connectors without cutting or splicing your original wiring.

No cutting. No splicing. No permanent modifications.
