I'd say it's safe to call them HID's. They are, after all, High Intensity Discharge headlamps regardless. (However, if there's a filament in there, they techincally are supercharged halogens, buring at a high temperature and color.) If WannabeH3 called them Xenons, then I'd have a problem too. Xenons are as mentioned an arc of electricity through xenon gas, of which the arc is what actually produces the light. Pretty cool, but extremely expensive to buy and replace. I cringe when I see a car with a burned out Xenon. It's usually around $700-$1,000 for a new one, since the entire head unit must be replaced, or so I've been told.
