I used to have some "light smoke" vinyl film on my stock 07 tail lights and third brake light which matched my ~35% window tint pretty well. I think I purchased the film from HotSubarus.com, but that website no longer exists, however, you can find a comparable product at several other websites. When I bought my 04/05 tail lights, I decided to remove the film and sell the 07 tail lights in stock form. Peeling the film off took more elbow grease than I expected because it was stuck on there pretty good (even after several years). When the film was finally off, I was left with a good amount of sticky residue on the surfaces that took quite a while to remove using Goo Gone and many paper towels, but the lights ended up looking brand spankin' new. Unfortunately, I don't have any pics of the lights illuminated, but even with them only being lightly smoked, the amount of light put out was significantly reduced. At times, it was hard for me to see at night when I was backing up, so be prepared to deal with that.
