Real Glass Lenses – Not Plastic

RMS Lighting Gen1 housings feature real glass lenses with durable metal backs.

Unlike many lower-cost conversion kits that use plastic housings, our glass lenses maintain their clarity and will not yellow or haze like plastic lenses over time.

This gives you the durability and classic appearance enthusiasts expect from an OE-style headlight conversion.

Built-In CANBUS Technology

The included 30,000LM H4 bulbs feature a built-in CANBUS driver designed to provide reliable LED performance across a wide 9–32V operating range.

Combined with customized CSP3570 LED chips and an active cooling system, these bulbs are engineered for powerful, dependable illumination.

Adjustable Beam Alignment

The 360° adjustable rotating bulb base allows the LED bulb to be properly positioned inside the housing for optimal beam alignment and light distribution.

Combined with the correct Left-Hand Drive (LHD) lens pattern, the Gen1 housings provide controlled road illumination while maintaining the traditional appearance of a sealed beam headlight.

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.
