Are you blind as well as stupid - my details are (a) in my sig, (b) in my profile.
Sean - you may well be posting some very useful, important and helpful information, and everything you've said about Xenons may be correct - it certainly all sounds impressive! - and this is obviously a subject you feel strongly about, but you are very aggressive, if not downright rude and offensive, in the way you are putting this message across, so it's not surprising that you are putting some people's backs up.
If you wrote in a slightly less confrontational way (see Doc's post for examples), then people might be more ready and willing to take your advice. 
OK Alex, you
may have a point, and I appreciate your concern

. I
may come across strongly on this issue, but I consider it reasonable for my "enthusiastic" and "robust" answers as follows.
Firstly, the "blind and stupid" bit IMO was perfectly justified, as I have NEVER hidden my details. In fact, the OP has hidden
his details!
Secondly, there was a detailed thread on retro-fit Xenons not many days ago, which the OP could have searched for!
Thirdly, it is perfectly clear the OP is either spamming, or is on some kind of commission. I base that opinion on (a) the OPs posting history from his profile, and (b) who would have the necessary MoT beam testers for the pictures he posted?

Next, the OP posted "
At the moment their legal, but there is a grey area as to the futur of retro fit Xenon's, for factory fit they have to have headlight washers and self leveling, however there's no such rule for retro fit at the moment.
Swaping back to halogen bulbs on the Mk5 is a 10 minuet job.".
This is a statement from the OP stating they ARE legal, when they are not, the OP IS aware of the requirement for headlamp washers and auto leveling, but again wrongly quotes of no such requirement at the mo, and finally, states about swapping back to halogens in 5 minutes - why? If his Xenons
were legal, then why the need for such a statement - my guess is the OP
does know they are illegal, and is merely trying to cover his ar$e, at the same time drumming up more sales/commission for future fitments!
If I have offended the OP, then tough - if I have offended anyone else, then I offer my appologies for the tone and manner for my expressions in this thread.
At the end of the day, it is only my opinion, based on my qualified experience, of both the law and motor vehicle maintenance. If people wish to disagree, that's fine, it's a free country, where freedom of speech and expression is still legal fx/on <looks over both shoulders> fx/off.
If I can offer my utterly impartial advice, on any subject which I have a good knowledge of, then I am only too pleased to do so. For me to stay silent on a subject which I
do have knowledge of - well I wouldn't be being fair to the whole of the GolfGTI forum!
