They wont pass the MOT if they aren't aligned correctly thats all, but bear in mind if you dazzle a copper they'll pull you and order you to remove them and produce / issue a fine ( no points ) plus I'm a hater of these things, they are a complete menace when someone blinds you with them and they near enough always do. just get some decent bulbs in.
Plus Xenon bulbs and White LEDS doesn't look right either imo.
aligning them is soo easy one allen key a garage/ wall with the L shaped line accross it on paper, turn the lights on about 5foot from the wall and adjust the two allen key points on the back of the lights big yellow things move the light beam up and down untill level, sorted or pay a garage a tenner to do it and double check it will pass an mot with the machine, ive never been flashed, only used top quailty stuff, clean lenses all the time, and i drive past mod police and a station on my way to and from work, with lights on and never been pulled never had any one second look them either and if you go with 6000 or 4300K no one will question them as they look white just like the audis and mercs and they do look good with philips 6000k led side lights as they match the dipped lights too. yes you get some people that blind you but look who is driving 99.99% of time its an old golf or chav driving and they dont 'care' think they are above the law, if i get told to take them out once i wont use them again but until then and if i keep passing mots i will use them legal or not, 31 in a 30 is illegal too sooo i betting everyone does that too
