The Morimoto XB LED Headlights and Tail Lights for the 2015-2019 GMC Sierra 3500HD Dually are made to improve how your truck looks and works. The headlights use bright Osram LEDs and quad-projector lenses to help you see better, day or night. They also have a daytime running light with a cool C-shape and a turn signal that can blink in sequence. They meet DOT and SAE rules and are easy to install with a plug-and-play design. Built with strong materials like UV-coated lenses and aluminum heat sinks, they’re made to last. The matching tail lights also use bright LEDs and a modern design with floating 3D light blades for brake and turn signals. They come ready with bright reverse lights and work with an optional Backup-Boost light bar for even more brightness when backing up. These lights are safe, stylish, and tested for quality. With strong build quality and a sleek look, they’re made for Sierra Dually owners who want better lighting and a clean design.
