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 H13/9008 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.

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.

Excellent output in my Super duty.

5 out of 5 stars

Great quality, little pricey but very bright.

Cole Dehne  

Easy install, quality build, ultra fast shipping. Little pricey but the quality stands up with the price and so does the light output. Had to adjust the lights in order to avoid blinding people oncoming. 10/10 would buy again.

I wish I would have ordered these sooner!

Anthony Pompa  

Lights are super bright, without blinding oncoming drivers. These headlights made a huge difference on my Ford E350 van. The light pattern is full and lights up more area than the stock bulbs. The difference is amazing. If you are on the fence about ordering these, do it, you wont be sorry. Be sure to check the light pattern when you install them, I had to rotate the bulb after originally installing to get a full, complete light pattern.

These lights are extremely bright and white. Light goes alot farther than any lights I've seen. Love them so far, hopefully they last long. But they do have a warranty! Build quality is very solid:call_me_hand::skin-tone-4:

LED upgrade

Vincent Foster  

I have only had them for about 3 weeks but it a noticeable difference. Very pleased with them. The lights themselves were very easy to install, Dodge's engineers on the other hand not so easy. (you have to go thru the wheel well to get to one of the bolts) I put one of them in tilted in the wrong direction and had to adjust it the next day but no issue turning it. Very happy with the lights.

Kenneth Granato  

These are great headlight bulbs. They are a 100% better than the previous version. There in no shadowing or scattered light. More direct lighting and much better low and high beam distance.

These lights work great and we're easy to install. You do have to understand there is an up and down on these lights and they can be installed upside down.
