Designed for 5.75-inch round headlight housings, this LED replacement cartridge offers a seamless blend of vintage aesthetics and cutting-edge technology, delivering both high and low beam functionality with superior performance.
Traditional sealed beam headlights, while iconic, often struggle to provide adequate brightness for safe nighttime driving. The RetroBright LED Replacement Cartridge transforms your driving experience by offering significantly enhanced visibility. Emitting a crisp, clear 5700K light, this LED bulb ensures you can see the road ahead more clearly, making your nighttime drives safer and more comfortable.
One of the key features of this LED cartridge is its plug-and-play compatibility. Designed with standard H4 wiring and a 3-pin configuration, it easily integrates with your vehicle’s existing electrical system without the need for cutting, drilling, or complex modifications. This straightforward installation process allows you to upgrade your headlights quickly and hassle-free.
LED technology brings a host of benefits compared to traditional halogen bulbs. The RetroBright LED cartridge takes up less space, generates significantly less heat, and consumes less power, making it a more efficient and long-lasting option. In fact, this LED bulb offers up to six times the lifespan of a standard halogen, reducing the need for frequent replacements and lowering maintenance costs.
The low-profile housing design ensures that this LED cartridge fits perfectly into most shallow headlight buckets commonly found in classic cars. Developed in collaboration with Morimoto, a leader in lighting innovation, this cartridge features a specialized PWM LED driver that maintains peak light intensity, even during prolonged use. Whether you're using the low beam or high beam, this LED cartridge provides consistent, reliable lighting performance.
Designed as a replacement for standard sealed beam headlights, this cartridge is ideal for those looking to maintain the classic look of their vehicle while benefiting from modern lighting technology. **Sold individually**, the RetroBright LED Forward Facing Light Bulb in Modern White (5700K) is the perfect choice for classic car enthusiasts who demand both style and functionality.

Auto Metal Direct is a team of true car guys with years of experience in sheet metal reproduction, car restoration and paint/body work. We believe that quality is not subjective! Our mission is to provide the best customer experience for the Ford, Mopar and GM classic car markets - both in products and in service.
Our panels are made from proper gauge steel and include all correct-as-original clips, tabs, flanges, bends and seams. Each time a prototype body panel comes off of a new tooling, we test fit it on a car. The marked up prototype is then used to change and improve the tools, and a new prototype is produced. This procedure might be repeated multiple times but, once the part is finally approved, you can be assured of a quality part.
