As long as we're on the topic of tail lights, I figured I'd share this. I spent a few minutes in photoshop last week and came up with these. I know the pictures aren't awesome quality and this is not what I'm planning for my car or anything like that, just basically another possibility for those that like to get into their bodywork. I think it could look half decent if done right.
