GTR Lighting is an automotive LED lighting brand focused on high-output LED replacement bulbs for factory halogen housings. The brand is best known for its Ultra series, which has progressed through multiple generations with the Ultra 3 being the current flagship as of 2025. GTR products are sold through specialty lighting retailers including Headlight Revolution and The Retrofit Source, and are tested and reviewed by independent lighting benchmarkers.
GTR Lighting positions its products at the premium end of the LED upgrade market, targeting enthusiasts who want maximum output in their existing housings. The brand backs the Ultra 3 with a lifetime warranty. As with all LED replacement bulbs in halogen housings, GTR Lighting's products are sold for off-road use only in the US, as no FMVSS 108 certification pathway exists for LED-in-halogen-housing combinations.
