The Morimoto XB LED Headlights and Tail Lights for the 2014-2018 GMC Sierra 1500 offer a big improvement over the stock lights. These headlights look great and are built to last a long time, with a strong warranty and high quality materials like UV-coated polycarbonate lenses and die-cast aluminum heat sinks to keep them cool. The bright Osram LEDs provide clear daytime running lights and full sequential turn signals for better visibility and style. They are easy to install with plug-and-play wiring that works with the factory connectors and won’t cause error codes or flickering. The tail lights feature powerful LED brake and turn signals with a modern 3D design, plus an optional LED reverse light bar for extra brightness when backing up. All lights meet DOT and SAE safety standards and come backed by a five-year warranty, making them a reliable and stylish upgrade for your Sierra.
