Introducing the Morimoto X3B LED Brake Light Upgrade for 99-16 Ford Super Duty trucks. This innovative upgrade combines style, performance, and utility, addressing the long-standing need for a modern third brake light. The X3B features 3D red brake light optics for a contemporary look, clear optics that illuminate the truck bed, and a sleek piano-black polycarbonate housing. Its quad brake light optics, composed of optical-grade red polycarbonate and powerful 3W LEDs, ensure high-intensity visibility day and night. For added flair, an optional F1-style rapid flash module (SKU X3B01) is available. Unlike typical afterthoughts, the X3B includes purposefully designed rail-style bed optics that eliminate dead spots, making it a practical upgrade for truck enthusiasts. Installation is a breeze as it utilizes existing mounting points and plugs into the stock wire harness with no modifications required. Plus, it complies with all DOT and SAE regulations and comes with an industry-leading five-year warranty for peace of mind.
