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.
