Morimoto X3B LED Third Brake Light for 2014-2018 Chevrolet Silverado 1500

Upgrade your 2014-2018 Chevrolet Silverado 1500 with the Morimoto X3B LED Third Brake Light, engineered to replace the factory third brake light with a premium LED assembly that combines modern styling, exceptional visibility, and practical cargo bed illumination. Designed for enthusiasts who refuse to settle for outdated factory lighting, the X3B delivers the perfect combination of performance, functionality, and OEM-quality fitment.

The X3B features a sleek piano black polycarbonate housing paired with bold 3D red brake light optics and crystal-clear bed light lenses, creating a refined, modern appearance that perfectly complements upgraded headlights and tail lights. Its premium design gives your Silverado a clean, factory-inspired look with significantly improved functionality.

Performance is equally impressive. The X3B utilizes four jewel-style optical-grade red lenses powered by high-output 3-watt LEDs, producing an exceptionally bright brake light that's easily visible in both daytime and nighttime driving conditions. For added safety and attention when braking, the X3B is also compatible with Morimoto's optional F1-style rapid flash module (SKU: X3B01).

Unlike many factory third brake lights, the X3B also features powerful integrated cargo bed lighting. Precision-engineered rail-style optics distribute light evenly across the truck bed, eliminating dark spots and providing excellent illumination when loading or unloading cargo after dark.

Installation is quick and hassle-free. The X3B reuses the factory mounting points and plugs directly into the original wiring harness, requiring no cutting, drilling, or vehicle modifications for a true plug-and-play installation.

Designed to meet DOT and SAE requirements for rear-facing lighting, every Morimoto X3B is independently tested to ensure exceptional quality, safety, and reliability. Backed by Morimoto's industry-leading 5-year warranty, it provides long-lasting performance and peace of mind.
