Sealed LED Headlamps
Truck-Lite revolutionized night driving with their 7-inch round and 5x7-inch rectangular LED headlamp replacements. These drop-in headlights replace dim, outdated sealed beam halogens on older trucks and Jeeps. They draw incredibly low amperage and produce a brilliant, pure-white beam pattern that mimics daylight, drastically reducing driver fatigue.
Super 44® & Marker Lights
The Truck-Lite Super 44 is the industry standard 4-inch round Stop/Tail/Turn light found on millions of semi-trailers. Upgrading to Truck-Lite's sealed LED versions eliminates the constant hassle of replacing broken incandescent filaments. Their epoxy-encapsulated electronics are completely impervious to moisture, road salt, and heavy impact.
Frequently Asked Questions
Are Truck-Lite LED headlights street legal?
Yes, Truck-Lite LED headlamps are fully DOT-compliant and meet strict Federal Motor Vehicle Safety Standards (FMVSS-108). Their complex reflector optics are engineered to keep the massive LED light output focused safely on the road without blinding oncoming traffic.
Why do commercial trailers use sealed lights with pigtails?
Commercial trailers endure massive vibration, which destroys hardwired connections. A sealed light uses a weatherproof plug (pigtail) on the back. This prevents water from traveling up the wire and corroding the trailer's main electrical harness, and allows a driver to swap out a damaged light in seconds without wire strippers.
