Taillight tint

I have seen a few GP's with what looks like tint over the tail lights. I know theyre not covers, they just look like stock tails with something over them. Has anyone done this or no what im talking about. What is used to do this, im interested.

i know what your talking about and its just regular window tint. Theres a forum on fullthrottlev6.com about it under W-Body Apperance, check it out
