Complete H4/9003 HID Kit: If you've been looking for a complete one-stop-shop kinda kit to run HIDs, this one from GTR Lighting has been painstakingly designed to optimize performance and reliability. High-quality materials are everywhere and the output is exceptional from the Ultra Series HID bulbs. Expect it to impress all your friends.

The Pinnacle: One of the HID bulbs that put GTR Lighting on the map was this, the Ultra Series. It provides a seriously powerful upgrade to anyone looking to go from halogen to HID.

Precision: One of the hardest things to do in HID lighting is to get the alignment of the bulb itself in the halogen-based housing. Without that, no amount of tweaking and modification is going to get you proper lighting. Thankfully, GTR went to painstaking lengths to ensure an absolutely perfect alignment with the Ultra Series. Each and every bulb is laser aligned into the housing and checked for fitment before it leaves the factory.

Materials: To ensure that alignment doesn't go to waste, GTR uses the best Philips UV Resistant Quartz available. It won't dim and fade fast like lesser alternatives. It comes standard with insulated wiring to make the connections from your AMP style connectors to your ballast as though this harness came from the factory itself. No cutting, no soldering, no splicing. Just plug-n-play performance.

Benchmarking: GTR Lighting didn't design a ballast with simply their own product in mind, they built it to outperform the best of the best in the business. That's why you'll appreciate that the Ultra Series HID Ballast is quieter the competitors while also providing a lighting quick ignition of intense brightness in just .1 seconds with complete power in only 9 seconds. The assembly itself is built to handle the roughest trails, tracks, and weather you can throw at it. This ballast is the complete package.

Installation Ease: Coming in at an incredible compact 2.75x3.5 inches, thisballast is small enough to fit almost anywhere and has complete mounting hardware as well as a grounding strap included.

Flicker Free & No More Bulb Out: Thanks to intelligent Canbus integration technology and an ASIC controller, these ballasts can handling pulsed width voltage or even a complex Canbus circuit. By leveraging those innovations you'll never get lamp out warnings, bulb out warnings, or flickering lighting. GTR really did think of everything.

Body: The high-quality materials will have you proud of your purchase too. The harness itself is 13 inches long, providing more than ample installation flexibility. The body of the ballast is shockproof to handle all of the roads' bumps and bruises, and the outer layer of the wiring loom is fitted with abrasion-resistant mesh so you can count on this ballast to have no weak links.

It don't work for 2015

by -

Instruction should be a little bit more detailed as far as it not working for 2015 Ram 1500 models. It Turned off on me in the middle of the freeway. Use the morimoto wiring harness for ram with this product if you're going to install it on a 2015 ram 1500 models. But other than that awesome light.

Best quality hid kit


Had some amazon led in

by -

Had some amazon led in before and these blew them out off the water in every way. Eventually when the bulbs burn out I'll go from 8k to 6k for a color closer to that of the suns.


Extremely Bright!


I have an '18 Toyota Highlander with horrible stock halogen lights. I've been looking around for better lighting options, and initially I tried LEDs for my low beams but they still didn't perform well enough due to the projector lens. The staff at HR highly recommended this GTR 55w HID kit, and I must say it is a vast improvement over anything I had before. I tried different temperature bulbs, but long story short I called HR due to some bulb issues (different colors within the pair, maybe defective pair, etc.). The bulbs I have now are 6000k, and the light output is diamond white with a blue hue. Not only is the output super bright, I love the color because it gives a hint of blue. HR customer service is excellent as they were extremely helpful via email and phone, and they sent me new bulbs within a week. They really want to be sure their customers are happy and taken care of.

Some things to note. The bulbs can run very hot. HR told me stock housings are high quality and can withstand high heat, so I'll be monitoring my lights regularly. I've read other customer reviews and I haven't come across any issues though. My low beams require dust covers, so it took a bit of work to use a cone bit to drill just shy of an inch circle like the HR youtube video shows.

Overall, I am very happy with this purchase. I can finally see well at night, especially when I am well outside of the city. I put LEDs in my fog lights and high beams, but I rarely ever use them anymore because my HID low beams are more than adequate. If you are looking for a substantial upgrade for your low beam projectors, this is the kit to get!

This product is fantastic in it's ability to produce a super bright output. I will be purchasing conversion kit's for our five other vehicles in short time. Great quality and design by the engineers and that's tough to say when I work with engineers all day and I know how big their ego can be. Never the less, GREAT JOB ON ENGINEERING THIS PRODUCT!
