swapping headlight bulbs with HID bulbs

[Jeph]

denverpete is right about retrofitting an aftermarket HID kit. It may not be as effective as your existing halogens.

Furthermore, I attempted to install an aftermarket xenon kit... the xenon lamps were actually too long (or tall) to fit in the compartment in which the bulb is located. There's a little light shield thing that prevents the lamp from fitting. I hope that makes sense. Other xenon kits may have shorter H7 lamps that would fit, but I think you'd be better off with maybe some SilverStars ($30-40?) or Porsche Litronics ($1200ish).
