So youre eager to get a blackout on those tail lights, but not so sure if theres actually any tinted tail light law against it.

This is a tricky one, most states would consider it illegal as they obscure your signaling and a lot of the time are not that visible at night. There are states where you could probably get away with a really light tint as long as your lights are bright enough. However, you run the risk of getting a hefty ticket, so to be on the safe side, rather stay clear of getting a tail light tint all together.
