There are other ways to rig our lights to accomplish what the BriteBox does. Using relays to keep them on. I'm going on 3 years using my BriteBox and have only had one problem. And that was my fault because I cracked the connector changing bulbs and one of the pins backed out slightly. It would work good untill It got wet while driving in the rain. My left side lights would stay on after turning off my headlights. But after about 5-10 minutes they would also go off.
Our trucks have a built in feature to turn off our lights if we forget to trun them off when getting out of the truck. That's what would turn mine off.
If your lights stayed on for the whole night, or for 3 days, you may have another problem that is not related to the BriteBox.
I don't know why my bad connection caused my light to stay on after turning off the switch, or how the BriteBox played a part in the problem. But since I fixed the problem that I caused, mine still work great.
