My opinion: I don't get it, why would you decrease the intensity of your reverse lighting? I actually want to put brighter bulbs in mine.
Lol. I have tinted windows ( 10% front and 5 rear). It's terrible backing up. I wanna put backup lights too. Before I ram some dudes civic.
Tinting reverse lights looks cool ( on certain cars) but definatley doesn't serve a purpose.
Roverrad- post a few more pics. The ones you posted are bad angles.
