okay, i think you're talking about just plug-in bulbs, and not the entire HID system with the ballasts. since they're the "super white HIDs" then you would be okay just to plug them in, but from what i hear, SOME few cars have problems with burning their wire harnesses, so there isn't too much risk involved. i'm running those and they worked just fine for the past couple years.

if you really did get real HIDs, they should have much lower wattage (like 40/45w or something) because they generally require less current from what i understand, but i could be wrong too.
