Wow, I can't even picture that in my head. Why do you want to mess with your taillights? Blacked out tails look stupid too, just leave them alone..

If you're really deadset on making something that ugly, don't start with red tails, because they'll end up pink with any kind of non-opaque paint or gradient film on them. Start with clear tails and go from there. It's all illegal, so you might as well go with as many illegal parts as you can.
