As above, you need a red reflector on each side of the vehicle for uk regs, also if you are to tint/smike your lights dont go overboard as they need to be as visable as possible when iluminated especialy when it comes to the police. (also you dont want a shunt up the rear end because you lights arnt visable ) i did a nice light smoke on the outside of the lense on my td5 disco just using an ordanary black spray can even over the reflectors and never got any bother even passed mot's. hope this helps, cheers -J-
