incorrect.. the city lights do not have anywhere near enough wattage to change the color of our HID's.. you could put any color in there and it won't change a damn thing about the HID's.. trust me. i've tried blue, red, purple, hyperwhite, etc. also, since these lights are so small, its hard to detect..so even if you have an illegal color in there..it would be hard for a cop to notice..unless you're driving in the dark late at night behind a cop with only your parking lights on...
