Re: HID: anyone try to fit one in?
I've seen the H1 HID conversion kits and was tempted. They actually seem to draw less current than incandesent lamps. In terms of power consumed it's something like 35w as opposed to 55w. Some kits I was looking at seemed quite well thought out. The ballast would connect directly to the headlamp connector (no cuts), and the HID capsule had a H1 base that would fit in the headlamp housing at the correct depth. You'd have to fit the balast in a suitable place.
The problem lies with getting it through an MOT if fitted to a UK car. HID equiped cars need headlamp washers and an automatic beam leveling system to pass an MOT. The manual system fitted to the 155 isn't good enough. Depends on who does your MOTs ands wether they'd notice, but technically you couldn't get away with it.
I ended up fitting good +50% halogen H1s and I'm quite happy with those (Osram SilverStars).
