The Morimoto XB LED headlights and tail lights for the 2015-2019 GMC Sierra 3500HD Dually give your truck a sharp, modern look and better lighting performance. The headlights use Osram 5000K LEDs for bright daytime running lights and a turn signal that can flash in sequence or a regular on-off style. With quad-projector lenses, they meet DOT rules and are easy to aim. Installation is simple with plug-and-play wiring that works with halogen or HID setups - no flickering or errors. Built from strong materials like UV-coated lenses and aluminum heat sinks, they’re made to last. The tail lights also offer bright LED brake and turn signals, with 3D blades that stand out day or night. They come ready with LED reverse lights and can be paired with an optional 2,700-lumen backup light bar. These lights meet all safety rules and are tested for quality. With red or smoked lenses and sleek styling, they fit the truck perfectly and add both safety and style to your Sierra Dually.
