I purchased a HID kit from HID Conversion Kits, Xenon Lights, Headlights, Bulbs, and installed them yesterday, they say the 50watt ballast will work with the on board computer (Trick the system) and keep the lights on (Not true). Don't waste your money unless your willing to make some mods. I have ordered (4 each) three ohm 50 watt resistors and will have to install them two resistors for the right and two for the left light. The HIDs will come on with the engine off but as soon as I start the truck the lights will not come on. Once the HID ballast warm up the lights work great. The Hi/Lo feature is cool.
