PRODUCT DETAILS

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 forward facing 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. Improving the style, performance, and night time driving experience for our customers are all priorities here at GTR Lighting.

Nice Fit
Color: Black, White, Light Gray, Size: 3X-Large
I picked this up looking for something simple but clean, and it delivered. The fit is comfortable, the material feels solid, and it looks good without needing much effort. It’s one of those pieces you can throw on and still look put together.

Good value, soft and comfortable
Color: Black, Army Green, Light Gray, Size: 4X-Large, Color: Black, Army Green, Light Gray, Size: 4X-Large
Initial thoughts are very positive with this 3 pack shirt set. The green is similar to an OD military green and the black and gray are standard color shades. Material is soft and sizes are true to size. The mock turtleneck isn’t too tight but may still be a little annoying to some people. I do question the amount of spandex in these shirts. Tag says 5% but these shirts are extremely stretchy and feels like a higher spandex content. It’s also a little tough to figure out which way is the front of the shirt. Visually rhe front does have a lower collar line than the back but would still be nice to have a brand tag printed in the back of the shirt for quicker identification. Overall for roughly $12 a shirt these are a good choice for everyday wear. I will update rating if these shirts fail to meet expectations after further use.

Just what I wanted.
Color: Black, Navy Blue, Wine Red, Size: 5X-Large
These may have just become my standard shirt to wear. Feels good whether tucked or out. Drapes well and fits well. So far, I can see it adjust to the different undershirt I may wear. Will probably order another set in other colors and a back up set of the basics because they will get worn a lot.
