FYI.....you are asking for the police to pull you over with HIDs on your rig. If they didn't come stock, then they're illegal. No one makes a DOT HID kit for any vehicle, this is because you can't go changing the style of light (incandescent - HID) on a vehicle. The police are starting to crack down, and I know a few of the traffic guys have started impounding for them. If you have anything else that may be questionable on your rig (ie mudflaps, fenders, etc), then I wouldn't suggest it as you're asking for them to look at you a whole lot more.
The light output from an HID bulb is completely different than that of a regular bulb. When a retrofit HID bulb is put into a standard housing, the light is not reflected the same way. A proper housing is needed for HID bulbs otherwise all that happens is that you have light going everywhere. This is often mistaken for having a better bulb as you can "see alot more" or "the road is lit up better".
I know that there are all types of "offroad use only" items out on the market, but there are alot of places that are selling HID retrofit kits and downplaying how illegal they are. I am not innocent when it comes to using an "offroad use only" item on a vehicle I've owned, but these kits blind oncoming drivers and pose a big safety risk.
Sorry....just my .02. I'm jumping off my soapbox.
