Morimoto GMC Sierra (14-18) X3B LED Third Brake Light

Brake & Bed Light Upgrade

This Morimoto X3B LED upgrade combines contemporary styling with practical performance for 14-18 GMC Sierra trucks. The assembly features quad brake light optics crafted from optical-grade red polycarbonate, powered by 3W LEDs for enhanced visibility during day and night driving.

The sleek piano-black polycarbonate housing showcases 3D red brake light design paired with clear optics for bed illumination. Rail-style optics provide even lighting across the truck bed without dark spots.

Installation requires no modifications—the unit uses original mounting points and connects to the existing wire harness. An optional F1-style rapid flash module is available separately for added visual impact.

The assembly complies with DOT and SAE regulations and carries a five-year warranty from Morimoto, backed by their Atlanta support team.
