You can go to most any tint shop and they could do it for you. It isn't very hard and I had mine done here in Socal at http://www.stickercity.com/
I went to a professional vinyl shop hoping to have my taillights tinted too. In the end they couldn't do it with 1 piece of vinyl because of all the crazy curves. They said they can do with 2 pieces, but that would risk them peeling. So in the end I had to get a paint shop to tint them.
Pics?
Has anyone done front headlight tint? or changing the yellow side marker?
