smoke tails

I saw a 6th gen accord like mines the other day. It had a black taillights. It sure as hell wasnt altezzas because it didnt had the big red circle in the taillights. Im pretty sure its a stock taillight. I think he might of smoked it or tint it? How do u do this??

do u literally just use a match and smoke the taillights? WIll the brake light/signal lights be able to penetrate through the smoke???!?! If I do smoke it..will the plastic melt??how do u do this?!!! it looks way better then altezza!!!
