5.75" Gen3PRO Round Glass Sealed Beam LED Headlight Conversion Kit – H4 Mini Projector LED Bulbs

Upgrade your factory sealed beam headlights with modern projector-style LED performance while maintaining the original factory appearance.

The RMS Lighting Gen3PRO 5.75" Round Headlight Conversion Kit combines OE-style glass lenses, durable metal housings, and high-output H4 Mini Projector LED bulbs to deliver excellent nighttime visibility with a cleaner, more controlled beam pattern and sharper cutoff line.

Designed for classic vehicles equipped with 5.75" round sealed beam headlights, the Gen3PRO provides the benefits of modern projector-style lighting without replacing the classic headlights with modern-looking LED assemblies.

What Makes the Gen3PRO Different?

The biggest difference is the H4 Mini Projector LED bulb.

Instead of relying solely on a traditional reflector-style LED bulb, the Gen3PRO incorporates a Mini Projector into the H4 bulb itself to produce a cleaner, more focused beam pattern with a sharper cutoff line.

This provides improved road illumination and better control of the light output while maintaining the classic appearance of an OE-style glass headlight.

Classic Look. Modern Projector Performance.

Cleaner Beam Pattern & Sharper Cutoff

The H4 Mini Projector LED bulbs are designed to produce a more defined beam pattern and sharper cutoff than conventional reflector-style LED replacement bulbs.

The more controlled light output helps put the light where it's needed on the road while reducing unwanted light scatter.

The adjustable rotating bulb base allows the projector to be properly positioned for optimal beam alignment and performance.

Keep the Factory Look

One of the biggest advantages of the RMS Lighting Gen3PRO kit is that you don't have to sacrifice the classic appearance of your vehicle to get modern lighting performance.

From the outside, you retain the appearance of a traditional 5.75" glass sealed beam headlight.

Behind the glass, you're getting the performance of an H4 Mini Projector LED system.

Real Glass Lenses – Not Plastic

RMS Lighting Gen3PRO housings feature real glass lenses with durable metal backs.

Unlike lower-cost plastic conversion housings, the glass lenses maintain their clarity and will not yellow or haze like plastic lenses over time.

This provides the classic appearance enthusiasts want along with long-lasting durability.

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.
