HID lights do not run at a higher wattage than Halogen lights, in other words they do not put out more heat. For comparison typical HID lights run at 35W, vs. Sylvania Silverstars, a performance halogen bulb, runs at 55W.
Dingo, after market HID lighting is illegal no matter what housing it's used in, whether it's a projector or not. It is only legal to use HID lights in OEM applications.
Unfortunately there was not much info on the whether you will loose your brights. So you Should assume that these HID lights are not a "Bi"-Xenon light so you will
completely lose your brights if you use this kit. Because of that i would not be interested.
