The Morimoto XB LED Silverado Headlights for the 15-19 Silverado HD. These headlights are a game-changer for your truck's lighting system. They draw inspiration from the OEM 16-18 Silverado 1500 headlights with LED Daytime Running Lights, delivering a factory-like appearance but with added features. Equipped with two high-output Bi-LED projectors per headlight, you'll enjoy four low beams and four high beams, providing exceptional illumination on the road. The LEDs are powered by Osram 5000K LEDs, ensuring optimal brightness during the day, and they dim when parking lights or low beams are active for compliance. The sequential turn signal adds a stylish touch, and you have the option to use it in standard mode if you prefer. Installation is a breeze as these headlights are plug-and-play, suitable for trucks with or without integrated LED daytime running lights. Their construction is robust, with UV-coated polycarbonate lenses, PPS plastic housing, and die-cast aluminum heat-sinks for durability and efficient cooling.
