4x6 Gen3 Pro Glass Sealed Beam LED Headlight Conversion Kit – Mini Projector H4 LED Bulbs

The Ultimate Upgrade for a Factory Look with Modern Projector Performance

The RMS Lighting Gen3 Pro 4x6 Sealed Beam Conversion Kit takes our Original Gen1 system to the next level by incorporating Mini Projector H4 LED bulbs. Unlike traditional LED bulbs, the Gen3 Pro projectors produce a significantly cleaner beam pattern with a sharp cutoff line, providing improved visibility while helping reduce glare for oncoming traffic.

If you're looking for the best beam performance while maintaining the classic factory appearance of your vehicle, the Gen3 Pro Kit is the perfect solution.

What Makes the Gen3 Pro Different?

The biggest difference between the Gen2 and Gen3 Pro kits is the LED bulb technology.

The Gen3 Pro features Mini Projector H4 LED bulbs that create a true projector-style beam pattern with a crisp cutoff line similar to many modern OEM vehicles. The result is more usable light on the road, better light control, and a premium driving experience.
