This is from a website that sells the HID kits you bought, this was taken from Xenonking.com FAQ.
(5) Are these HID light systems street legal?
NO XENON HID conversion kit available from any source is DOT approved if installed outside of the factory. 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.
From my research is has to do with the headlight assembly design. HID systems reflectors are set up different than halogen. You can buy them, but can still get a ticket for using them on any street. I guess it depends on the police officer. I just want people to be informed as I wanted to purchase HID for my edge until I did more research on it.
