  • Do I need PWM / Anti-Flicker Modules?: When using in Fog Lights: Unlikely. With low beams that double as Daytime Running Light: Likely.With high beams that double as Daytime Running Light: Likely. When the vehicle is late model American (Chrysler, Dodge, Jeep, Ford, GM): Likely.


APPLICATION: HID and LED bulbs are street legal in the USA for Fog Light use only. Not compliant with DOT / FMVSS108 and not street legal in the USA for Headlights. Legal for off-road use in Snowmobile and ATV headlights and off-road racing use only auxiliary or forward lighting. International street legality varies by country.

Note: This usage regulation is not unique to this item. All LED and HID bulbs from all other brands, regardless of marketing claims, are prohibited from street use in halogen headlights in the USA.




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 HB4/9006 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.

The GTR Ultra Series 2.0 fog lights and headlights are excellent. High quality. Lifetime warranty. Amazingly bright. The beam spread improves far left and right visibility significantly. Visibility forward is very impressive. Customer service is excellent. Shipping is quick. My wife feels much safer driving at night. Worth the money. 2020 Kia Sportage.


Worth the money


Installed in an 04 Miata w/projector housings.
What an incredible output from these. Excellent cutoff. And the hot spot is wide. These are everything the folks at HR say they are. I will definitely recommend these to anyone. And intend to use them in my high beams. The only drawback is you can hear the fans on them running. When outside the car, and for me when I'm in it. Note the car I'm using them in, though. A larger vehicle would probably mask the sound. I don't find this too be a problem. Just worth noting.


incredible, the GTR Ultra2's work better than expected in reflector housings

by -

installed my GTR Ultra2's in my Corolla reflector headlight housings, fairly fast and easy - drivers' side more challenging the battery doesn't provide alot of working space. had to clock my GTR LEDs at 3 & 9 o'clock (horizontal) the Allen key is supplied. many cars have DRLs which I bypassed on my Corolla so my Ultra2's are constantly on.


Absolutely Astounding


Switched from some "cheapo" Amazon bulbs over to the GTR Ultra 2.0's and WOW, they literally cannot be compared.

The beam pattern, cutoff line, overall brightness is FAR superior. Pictured below is my off-road truck showing how bright they are, (I need to re-align the cut off down a decent amount)


wont believe your eyes. Wow!!!!

Amazing is an understatement. You will not believe how much light this produces.


Bright Headlight, fantastic warranty

Just installed this light, very bright. The lifetime warranty is fantastic. Fast easy replacement. I had a LED headlight replaced, I just sent a picture of its destruction and HR replaced it with no problem.

I bought the Ultra 2's for my fog lights since I work a lot of nights. They really are super bright and I still have my great factory beam pattern. Next I'll be buying the same Ultra's for my low beams! Vehicle is a 2018 Ram Sport with projectors.
