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 H4/9003 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.

Let There Be Light

Dave Bertram

I'm a long time user of Hella H4 lights, first time for LED. Back in the early 80's when they were illegal for road use I had them, with 100 watt halogen bulbs. These LED's are as bright as they were, and the color temp is much better. My current set up is stock lamp housings on a Honda Element, and except for some minor shadows, they light up the road very very well. Aiming is critical to getting the light just right. Spent a few nites between each adjustment, and now they are dialed in. Have not been flashed by oncoming drivers. Light scatter is minimal, and beam pattern good. Highly recommend these, if they fit in your budget. Funny, after using these for 3 months, other vehicles lights appear yellow.

DIY Daylight!

Tubular Tokes

Bought a pair of GTR Ultra 2's H4/9003 for my 1983 Mercedes 240D. These fit in the stock 7" round sealed beam housings, even with the fan on the back of the bulbs. The LED module fits behind the headlight door on the W123 body cars. Direct plug-compatible replacement, super easy and super quick.

Great design. Really appreciate the detachable collar.

These are, by far, the brightest bulbs I've ever had on a vehicle! The low beams on these are easily twice as bright as the Sylvania halogens they replaced, and the high beams light up the road like daylight. I can see the road I'm on, the next 4 roads, and my entire future.

The "cool white" color, matches modern car's stock LED bulbs, but the brightness and light throw on these is like nothing else on the road. Will absolutely be purchasing for my other vehicle!

-1 star for the political statements on the packaging.

2010 Tacoma

Austin Murray

removed battery and window wash container / installed original rubber boots / installed bulbs in headlights (a little tricky to get spring clip closed with rubber boot installed) but fits together no problem / only thing I didnt like to much is I cant turn the bulb to be vertical to copy the orientation of the stock halogen bulb / the lights are very bright and shoot at least as far as the halogens but much brighter / I do not get flashed from oncoming traffic and did not adjust the headlights from where they were with the halogen bulbs / expensive but worth it / did not give full rating as I could not adjust the bulb so the led mounting strip is vertical

Upon initial installation, the bulb wiring were easy to zip tie out of the way and get everything situated. The gripe I have with the bulbs, the driver side bulb had a crisp clean line, like all the reviews that Headlight Revolution had stated. On the other hand, the passenger was very scattered and didn't have a definite cut off. I attempted to adjust the passenger side but that had no affect, just changed the angle of the horrible beam pattern. I thought this may stem from my housing/reflectors so I switched the driver to passenger and passenger to driver and the bleeding flood followed the passenger bulb. So if they were of equal quality, I would 100% recommend these, but they are not.

Needed more information

Michael Mangum

The headlights are exactly what is advertised. They light up a broad and intense beam without hazing the oncoming vehicles. The high beam is a very concentrated hotspot making night highway driving and off road much more comfortable than stock. I had a problem with the installation on the 2016 Tundra. Not enough info in instructions or YouTube videos, also had some issues with customer service at HR. Was able to get it sorted out with Ralph, he understood what my problem was on the backup lights and helped me, the install of the Ultra 2 headlights problem was corrected by disassembling the light to get it installed properly, without damaging the OEM equipment. Thanks for your help Ralph!

Excellent replacement for F55 MINI Cooper

anonymous

Bought these as a replacement for the halogens on my wife's MINI Cooper. Was initially concerned about figment but after being assured that if they don't fit behind the cap, I could return them, I bought them. They installed easily enough and after some measuring, I was able to make very slight adjustments to the elevation to have the same beam pattern as the halogens, only A LOT BRIGHTER.
