I found a set of headlights for my 1999 Passat (see link below), and I'm intrigued by them. I have a few questions, though, if anybody feels up to answering them. http://www.c3cars.com/parts.cfm?M=1&PMode=I&VIID=6197 1. They are projectors, but they use regular halogen bulbs. Is this kosher? I know that HIDs mounted in reflector housings are not only illegal but dangerous, but I've never seen regular bulbs in projector housings. Would this setup work better/worse/same compared to a reflector setup? 2. They don't say that they're US DOT approved. Then again, they don't say they aren't US DOT approved, either. What are the chances I'd be buying myself a set of headlamps that I'd have to get rid of in order to pass inspection? 3. These lamps come with levelling motors; that's a nice touch, but my stock lamps don't have levelling motors -- though they do have some of the gears in place. What would be required to use the levelling motors? Is the mechanism self-contained and powered from the same wires as the headlights themselves, or would I have to add extra power cables (and god forbid, an external controller) to use them? - - - While I'm at it, which aftermarket diverter valve is better: Forge or Hyperboost HX? The Hyperboost is prettier, but I'd rather have the beter one. Keep in mind that I'd rather have smoothness instead of absolute maximum performance.
