That's been my concerns, but as CJ says above I believe the lens are identical between the halogen and xenon units. I wasn't aware of the difference in the depth of the bulb and is something I'll look into. Ideally I'd like to see the inners of a xenon unit to see where the bulb sits in relation to the lens and compare it with my current halogen unit...

Just to clarify, what part do you refer to about the legality issue? I'm aware I'll have to reconnect/reinsert the fuse for my headlamp washer jets for MOT (a requirement for xenons), but I was under the impression that if the beam pattern falls within guideline then there won't be a problem with legality? Obviously I guess it could be the resulting beam pattern related to the bumb position discussed about which could scupper it. I could be completely naive here but would rather be corrected than be illegalcj10jeeper said:For sure as a cheap fix, not legal for many reasons, but often overlooked by MOT's they are OK.
