Our TRS Tested kits include all the right components to ensure perfect fit, function, and performance from the upgrade. At The Retrofit Source, we do 1999-2006 GMC Sierra LED lighting upgrades better!

This kit used to use the 3W CREE T10 bulbs but now uses the Carbide Series T10 bulbs. They are twice as bright and smaller so they fit more applications. This is a huge upgrade over stock and the old 3W CREE Projector bulbs. NOTICE: IF you are using the stock third brake light housing, the install is simple: Unscrew it from the outside and pull off the cover. If you’re using an aftermarket third brake light housing you might have to drop the headliner to get to the bulbs. We supply only the highest quality LED bulbs from GTR Lighting so you won't have any headaches and they will last a long time.These are easily THE BRIGHTEST LED bulbs that will fit in the GMC Sierra cargo light on either side of the third brake light.
