Add more light output and a modern appearance to your brake lights with the 921 XPR 3rd brake light bulb. Each of the four sides of this bulb is populated with 4 high power LED chips for maximum brightness. Housed in an aluminum casing with a textured finish for superior heatsinking properties, the XPR will last for years to come. Best of all, installation only takes minutes - simply take out your factory bulb and the XPR will fit snugly in the socket.


Instant Brake. The factory incandescent 3rd brake light bulb on the GMC Sierra 1500 lights up in a glow, which takes a moment to turn on. A modern LED upgrade provides instant response, which can alert other drivers on the road earlier, while also providing a modern LED appearance. This third brake light LED is a great upgrade in both style and function.

Correct Color. It comes in an intense red LED illumination, which is correct to SAE/DOT "red" requirements. This provides the most output through the red lens of the 3rd brake light, as the red lens acts as a filter, only allowing red light through. All Diode Dynamics LED lighting is rated with accurate, measured lumen figures, not calculations or guesses. We test the true output in-house, and provide you the real numbers to compare.

Reliability. Diode Dynamics LEDs are built with constant-current inductive circuitry, along with transient suppression. They are tested by our engineering team with a device that replicates years of voltage spikes, like the ones generated each time the alternator starts and stops on your Sierra 1500. This is what kills most LED bulbs over time, but just like factory components, Diode Dynamics LEDs are designed with built-in circuit protection. While more expensive than simple bulbs, this allows Diode Dynamics LEDs to last for years, with no flickering or failure.
Experience. After over a decade in business, Diode Dynamics is one of the most trusted names in automotive LED lighting. We directly assemble and engineer our own products in the United States, allowing for higher quality and performance, with the newest and brightest LED technology. Whether it's a GMC or anything else, we pride ourselves in offering only the best possible LED solutions.
