Finally, A Third Brake Light Worth Upgrading To

Your headlights and tail lights have probably already seen an upgrade, but that factory third brake light has been sitting there looking exactly the same for two decades, and the Morimoto X3B is here to finally change that. Built specifically for 2019 and newer RAM HD trucks, this isn't just a brake light swap, it's a combined brake and bed light module that actually looks like it belongs on a modern truck. Pronounced 3D red brake light optics give it real depth and attitude, while clear optics built into the same housing illuminate your bed, all wrapped inside a sleek piano black polycarbonate casing. The quad brake light design uses four jewel-like optics molded from optical-grade red polycarbonate, paired with powerful 3W LEDs for genuinely high visibility whether it's broad daylight or pitch black at night. If you want to take it further, Morimoto offers an optional F1-style rapid flash module, sold separately as the X3B01, for an added layer of attention-grabbing style. Installation keeps things simple too, reusing your factory mounting points and plugging straight into the stock wire harness with zero modification required. For a detail that most Ram HD owners never think to upgrade, the X3B turns a genuinely overlooked part into a standout feature.

Quad LED Optics Engineered For Both Visibility And Bed Lighting

The Morimoto X3B30 is an LED third brake light and bed light module engineered specifically for 2019 and newer Dodge RAM 2500 and 3500 HD trucks. The module features quad brake light optics, with four jewel-like lenses molded from optical-grade red polycarbonate and powered by 3W LEDs, delivering strong brightness and visibility in both daylight and nighttime conditions. Rail-style bed lighting optics are purposefully engineered to eliminate dead spots across the bed, giving utility-focused owners genuinely usable illumination rather than a token light that barely reaches the corners. The entire assembly is housed in piano black polycarbonate with a UV-resistant clear polycarbonate lens, built to resist yellowing and cloudiness over years of sun exposure. Installation uses the factory Mopar multi-pin OEM connector along with a plug-and-play adapter harness, requiring no cutting, splicing, or permanent modification, and the unit reuses all existing factory mounting points. For owners who want added style, an optional F1-style rapid flash module, part number X3B01, is available as a separate plug-and-play accessory. Every Morimoto assembly is verified by third-party labs for compliance with DOT and SAE regulations for rear-facing lamps, and this light is backed by a five year warranty.
