Overview

The RetroBright LED Forward Facing Headlight Kit is a 5.75-inch round LED headlight designed for classic vehicles. It offers modern technology with a classic white 3000K color temperature, providing superior illumination over traditional sealed beam headlights. These headlights are engineered for plug-and-play installation into your vehicle's existing harness without modifications, featuring a low-profile housing to fit most shallow headlight buckets.

Each headlight utilizes a PWM LED driver to maintain peak light intensity and is built with a UV-treated polycarbonate lens that is stronger than glass. The no-glare beam pattern meets or exceeds SAE and DOT requirements. These LED headlights are a direct replacement for sealed beam trade numbers 4000, 4040, H4001, H5001, and H5006, and use a PAR46 bulb type. Sold individually, order two for dual headlight setups or four for quad configurations.

The RetroBright LED Headlight Kit provides a modern upgrade for vehicles equipped with 5.75-inch round headlights. This kit delivers a classic white light with a 3000K color temperature, offering distinct low and high beam settings for optimal visibility. This allows for a straightforward replacement of older, less efficient sealed-beam units. The 5.75-inch round form factor makes them compatible with a wide range of classic cars, trucks, and other vehicles that utilize this specific headlight size. The LED technology ensures a brighter, more consistent light output compared to traditional halogen bulbs, enhancing both aesthetics and safety.
