921: GTR Lighting Ultra Series LED Reverse Bulb 921: GTR Lighting Ultra Series LED Reverse Bulb GTR Lighting 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. We’re on a mission: We know you don’t compromise on your vehicle and your lights shouldn’t be an exception. Our mission is to develop and supply the world with automotive lighting products using advanced technology that is truly an upgrade.

Great Lights, Check for Clearance Before Purchase

I wanted to be able to see when backing up and...problem solved! I like the creative solution the engineers used in replacing the whole socket so they could fit a massive heatsink on the ass end of these. That said, you'll want to make sure your application has room behind the socket location.

My Kia Stinger did not, but I was already balls deep, so now it does. It required removing one large tab of the heatsink (not recommended obviously) and plenty of internal sheet metal (non structural).

Definitely not plug and play for me, but the light's performance and quality are just what I needed!

Photos include output before and after with same camera settings.

Incredibly bright and easy install

Initially I had the xpr reverse bulbs in but for whatever reason they kept falling out of the socket inside my rear light housing. This led to many frustrating fishing attempts to get the bulb out. This bulb resolves that whole situation entirely by using a rubber grommet universal fitment while also being even brighter! These bulbs are also a little shorter lengthwise so may fit better in more applications. These bulbs are sold individually so buy 2 if you need a pair!
