This is a four-headlight conversion kit that swaps 5.75-inch round sealed beams for glass-lens housings with metal backs and H4 LED bulbs. Each bulb is rated 10,000 lumens at 6500K cool white and 50 watts, and the kit includes two harness adapters that mate H4 three-prong bulbs to factory two-prong high-beam connectors. It suits owners of classic cars and trucks with four round sealed beams who want brighter light while keeping the stock look. Against halogen sealed beams it is far brighter and whiter, but the cool white color and LED beam pattern draw mixed opinions from classic-car owners, and the adapters only cover the high-beam side.

This kit converts factory 5.75-inch round sealed beam headlights to LED while keeping the original look. It has four OE-style glass lens housings with metal backs and four 10,000-lumen H4 LED bulbs. The lenses are glass, not plastic, so they will not yellow or haze over time.
Installation is plug-and-play, with no cutting, splicing, or permanent modifications. The two included harness adapters connect the 3-prong H4 bulbs to factory 2-prong high beam connectors. Each bulb has an adjustable rotating base for positioning and beam alignment. The kit has the correct left-hand drive beam pattern.
The kit is designed for vehicles with quad 5.75-inch round sealed beam headlights, such as the Chevrolet Caprice, Chevrolet Impala, and other GM quad headlight applications. Some Toyota, Mazda, and other import applications may use a different pin configuration, and wiring and connectors can vary by year, make, and model. Confirm that your vehicle uses 5.75-inch round sealed beam headlights before ordering.
