2014-2015 GMC Sierra HD LED Reverse Light Bulbs: Looking for upgraded LED Reverse Light Bulbs from a reputable brand and value the fact that we've actually tested them on your truck? Our HR Tested kits include all the right components to ensure perfect fit, function, and performance from the upgrade. At Headlight Revolution, we do 2014-2015 GMC Sierra HD LED lighting upgrades better!

GTR Ultra: The original bad boy of backup LED bulbs is better and brighter than ever. With more light output. More reliability. More modern construction. A longer lifespan, all wrapped into the same universal package that made the original so popular: The new Ultra Reverse bulbs are the best way to back up with the visibility and safety that GTR Lighting customers demand.

New with Gen Two: As if the output from the first gen wasn't enough, GTR has upped the ante with the new Ultra version. Whereas the original version produced 1000 lumens each, the new Ultra bulb produces 1200 effective lumens, which is far more than what a typical incandescent bulb produces in the same application. The original used nine LED chips per bulb. Gen Two? Fifteen.

Control: But power is nothing without control! These bulbs illuminate from all four sides, and have a projector lens on the top edge, which makes them superior to alternatives because of the variety of ways in which bulbs can sit within their reflector housings. No matter if the bulb comes in from the side, or from the back of the housing -- this design ensures that the output will be maximized through a combination of reflected light (from your housing) and projected light (from the bulb itself)

Reliability: Whereas the old model actually had to be over-driven to squeeze more than the available amount of light output out of it's LEDs: The new version doesn't come close to it's peak. Not only that, but the thermal capabilities of the heat-sink on the base of the bulb have been vastly improved -- ensuring that these bulbs run cooler, last longer, and work more reliably throughout the course of their life.

Under-rated: When we think about lighting upgrades to enhance the safety of our cars & trucks at night, we always think about headlights and fog lights. Don't underestimate the luxury of improved rear-ward visibility though. This is overlooked far too often, but once you get used to having a set of these in your backup lights, you'll literally see what you've been missing all along.

Easy Install: Just remove your original backup light bulb socket from tail light. Remove old incandescent light bulb. Plug in new High Output LED reverse light bulb wiring into old bulb socket. Gently insert gray rubber grommet of new LED bulb into opening in tail light housing for reverse light. Push/twist new bulb gently until fully seated in tail light housing. Test function before re-assembly. Their universal design and fool-proof install make these one of the easiest upgrades possible.
