The Morimoto X3B (X3B50) replaces the factory third brake light on your truck with a modern LED unit that does two jobs. The brake side uses quad 3W red LED optics in polycarbonate with a 3D look, and rail-style white bed lights are placed to cover the dead spots a stock cargo lamp leaves, which matters if you actually work out of the bed.
It reuses the original mounting points and connects with a plug-and-play adapter harness to the stock wiring, so no modifications are needed. The X3B meets DOT and SAE requirements and carries a five-year warranty from Morimoto.
Fitment
2007-2014 GMC Sierra HD (2500, 3500 and HD models). It replaces GM part numbers 25890530 and 25834790. These lights were developed for North American vehicles; Morimoto does not guarantee compatibility on vehicles outside North America.
What's included
One X3B third brake light, a plug-and-play adapter harness and a replacement foam gasket. An optional plug-and-play rapid flash module (X3B01) is available separately if you want it.
Questions before you order?
Fitment questions are easier to settle before the box ships. Call or text Carl & Anton at (920) 249-7744 or use the chat — real humans in Sheboygan, Wisconsin, not a call center.
