How many bulbs do I need to order?

Different trim levels often come equipped with different third brake lights, so the number of bulbs needed varies. Please double-check your vehicle and select the quantity needed to replace all of your bulbs.

How bright are these bulbs?

The 921 XPR LED bulbs produce 60 lumens each, which is significantly brighter than your factory bulb. Diode Dynamics uses accurate, measured lumen figures, not calculations or guesses, to rate their LED lighting.

What does the warranty cover?

Diode Dynamics offers an industry-leading three-year replacement warranty on these LED bulbs. The warranty covers failures caused by defects in materials or workmanship.
