Update the look of your 2015-2019 GM Silverado/Sierra 2500HD/3500HD with the Morimoto X3B45 X3B LED Brake Light from XDP. This is a no-compromise brake and bed light that delivers the ideal pairing of style, performance, and utility, and it's offered for your GMC Sierra truck.

Detail-oriented enthusiasts who simply reject dull lighting should choose the X3B. The translucent 3D red brake light optics are as contemporary as they get while still being attractive. The bed's illumination is enhanced by the clear lenses, which are housed inside a piano-black polycarbonate casing. Here, form and function come together.

The quad brake light optics are both practical and aesthetically pleasing, bringing form and function together with the brake lights. A powerful 3W LED brake light arrangement is combined with four ornament optics made of optical-grade red polycarbonate to produce a high-intensity brake light setup that is clearly visible day and night.

Normally, the bed lighting is an afterthought, but not with the Morimoto X3B LED brake light modules. The entire bed will be effectively illuminated without any dead spots thanks to optically built rail-style optics. The X3B is a significant advance for truck fans who value utility and use their vehicles' bed in addition to their outside appeal.

The X3B plugs into the factory wire harness and reuses all of the original mounting points. It also fits exactly like the OEM brake light. Installation doesn't require modifications.
