depends, is it on the inside of the headlight? or outside? outside is easy as the guys have said... but inside is totally a different story,
i have mine , i think the HIDs exploded in them, and there stuffed on the inside...
i have got a quote, if its a soft seal, then it will cost $80 ea to open and polish on the inside,
if its a hard seal then it could cost any where up to $200ea
