Product Details

Craftsmanship: Designing a high-quality LED is a task GTR Lighting took seriously. Unlike so many companies that skimped on every single detail they possibly could, this H11 GTR Ultra Series 2.0 features a multi-faceted design that covers every base with real attention to detail.

The Best: While so many others use Philips or CREE LED chips, GTR went with a high-quality NLW753 option to ensure better results. Those results show through to the finished product too thanks to digitally optimized LED positioning that emulates the original filament location precisely. Combining these features is the key to getting all the light from the source to the reflector surface and ultimately onto your target without wasted lumens and glare all over.

Unstoppable: Consider this, GTR backs the performance of this LED light for life. They can be that confident because of all the work they've done to ensure it won't fail. The internals are 100% potted and waterproof for the wettest of trails or the heaviest rains. That means that the fan will never stop cooling either so temps never rise above 80c, well below the threshold for danger. They knew what they were doing when they assembled this rugged LED.

Better Fitment: We've heard many who assume that because the Ultra Series 2.0 is smaller than competitors that it's weaker and less capable. They couldn't be more wrong. Thanks to that small stature, it requires less energy to keep cool and keep power to the LED up. That results in 4100 lumens of output and a considerably easier time installing them. There are zero downsides here.

Best Warranty: We can't overstate this. You won't need another headlight bulb after these ones. They're so solid and strong that GTR backs them for life.

Open Box: Want to save a little bit of dough? Our stock of Open Box bulbs comes and goes, but when available, the deals are worth it! These bulbs function as good as brand new, but show minor signs of installation.

HR Tested: Here at Headlight Revolution, we spend a lot of time installing and testing the products you'll find for sale. We don't favor any particular brand, so our commitment to you is that we'll deliver the best product for your application, period.

Great LED replacements for wimpy halogen bulbs


Using these in projector housings. Fantastic light output compared to halogens! Beam pattern is very good, cut-off line is clear and there is no unwanted glare of any significance. I've also used SuperNova V.4's and I prefer these. The light seems slightly warmer and "fuller" to my eyes and I find that appealing. Stock H11 halogens are pathetic. These GTR Ultra 2's are a worthy investment so far and I highly recommend them, based on their performance in projector housings.

Pretty happy with it


Significant brightness improvement over halogen, and I found no light pattern issue.

It actually arrived defective, but Headlight Revolution swiftly took care of the problem. (Arrived faulty in perfectly sealed and undamaged packaging, therefore it's not even the fault of Headlight Revolution, probably a production oversight)

GTR Ultra 2

I think HR is the best company for buying headlights. I sent them an email asking for info regarding the product I want to purchase and they got back to me in a minute. Most companies won't get back to you before 24 hours or maybe a week. Order was shipped quickly and received without any problems. I own a 2016 Honda Civic, so installation took me less than 10 minutes. Personally GTR Ultra 2 is the best LED upgrade for your vehicle. They are little expensive compare to other brands but they're well worth it. I had another brand prior to this one and the difference is huge. Lifetime warranty is a big plus. Just purchase them and don't look back.
