Ultra HID H4 High/Low Bulbs: 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.
