Morimoto Chevrolet Silverado (14-18) X3B LED Third Brake Light
Morimoto X3B LED Third Brake Light — Chevrolet Silverado (2014–2018)
The X3B replaces the dated factory third brake light on 14-18 Silverado trucks with a two-in-one unit: 3D red brake optics facing back, clear optics facing down into the bed. The housing is piano-black polycarbonate, so it looks the part even before you hit the brakes.
Four 3W LEDs handle the brake function with good visibility day or night, and the rail-style bed optics spread light without the dark spots you get from a single point source. An F1-style rapid flash module is available separately.
