Just remember, HID kits are actually illegal unless you retrofit your headlights with HID optics. Without retrofiting, the nonHID lenses will distort the light and doesn't give the crisp cutoff and blinds other drivers.
http://www.intellexual.net/hid.htmlInstalling HID's into a vehicle not originally equipped with them from the factory is technically illegal. Practically speaking, you stand little chance of being cited for them provided you educate yourself on the requirements of HID lighting and take the necessary steps to ensure you have the right equipment and adjustments to keep it safe. That is, make sure your vehicle's headlight assembly uses an appropriately designed projector lense (as opposed to a reflector), and of course that your headlights are properly aligned after installation. Many newer vehicles use projector lenses because stock halogen bulbs also benefit from the "light shaping", but having just any old projector lense does not necessarily ensure that the beam pattern will be correct. It is absolutely essential for HID's to give the light output a sharp cutoff line to prevent blinding oncoming traffic. As HID's become more popular, aftermarket projector housings are being produced for some vehicles.The Department of Transportation (DOT) states that improperly-installed HID's are getting a lot of complaints. Vendors will usually include a disclaimer that they are intended for offroad use only, but it's no secret that people don't follow this rule. Now, there are a lot of aftermarket automotive parts that qualify as illegal but aren't strictly enforced. Logically, the safety implications of blinding oncoming drivers are more serious than, say, an exhaust that exceeds the legal noise level. So the DOT has actively gone after vendors of HID conversion kits, threatening monetary fines if they continue selling them, and consequently there are now fewer places to buy them.

Moreover, in the U.S, this is not street legal for use on public roads. As a result, we officially endorse the kit for exhibition and off-road use and will only sell the kit to be used for these purposes. We are not responsible for buyers who violate the terms of sale while in which they will assume all responsibilities for any unauthorized or unintended use other than exhibition or off-road use
