Style: Modern headlights have come a long way. Modern tail lights have come a long way... yet GMC is still specifying the same basic 20-year-old third brake lights on even their most modern trucks. Why? The X3B is the perfect grand finale for detail-oriented enthusiasts who just say no to stock. The pronounced 3D red brake light optics are as modern as it gets, yet tasteful. Complimented by the clear optics that illuminate the bed, and all wrapped up inside a piano-black polycarbonate housing. Here, form meets function.
Brake Lights: Here, function meets form, because the quad brake light optics are just as effective as they are attractive. Four jewel-like optics molded from optical-grade red polycarbonate paired with powerful 3W LEDs create a high-intensity brake light setup that's easily visible both day and night. An F1-style rapid flash module is also available, and easy to install (SKU X3B01).
Bed Lights: Are usually an afterthought, but not with the Morimoto X3B LED brake light modules. Optically engineered rail-style optics have been purposefully designed to effectively illuminate your bed without dead spots. While the X3B looks cool, its also a major upgrade for enthusiasts who value utility, and actually use their trucks too.
Easy Install: The X3B re-uses all of the original mounting points, fits like the factory brake light, and will plug into the stock wire harness. There are no modifications required for the installation.
Style and Safety: All Morimoto assemblies are designed to comply with all DOT, SAE regulations for rear-facing lamps. We pride ourselves on offering stylish, high-performance and safe products for serious enthusiasts, which is why all new Morimoto products are verified by trusted third party labs for compliance and are backed with an industry-leading five year warranty.
