Why would you want to have a "look" you can't see when you drive it, and is a perfect invite for someone to NOT see you in time due to darker tint.
Yeah I know its all personal...and to each his own. If that's what you want when you stand back and admire this fine car, then its your call for sure.
BUT besides the legalities, I would prefer those lights to be brighter personally. And a sequential top/window brake light might be a better use of money. ANYthing to keep people behind me from hitting me in the traffic.
But that's just one view...no pun intended.
