Doesn't mean it's legal for them to do it.I know several people who have been pulled over at night for no tag light. One of them got a DUI because of it. While DUI is certainly a crime he was committing, otherwise his driving was fine and had no other violations pertaining to any reason for being pulled over. How did the cop know he had been drinking? This was in Arab, and they were going to Wal-Mart for something. The cop told him he looked suspicious because they just circled Wal-Mart and headed back out. His wife had left her money at home and they were headed back to get it, they stopped him about a block from his house.
So yes in this state they will pull you over for no tag light, especially if you look suspicious.
I've got a modified tag mount because I installed a rear tire mount on the back of my Jeep. I hated how much space a full size spare took up in my back cargo area so I got a rear tire mount. It covers up the license plate, so my only option was to relocate the plate to keep it visible.
I've actually been wondering what to do about not having a tag light at night, but now - if I ever get pulled over for it - I'll just kindly remind them that it isn't against the law.
