Well, aside from night time rally cross, night time autocross and night time rally racing, why on earth would you want driving lights? They are illegal to USE in this state on the road. And when you talk to the sherrif, the border partol, or the warden, they seem hell bent on the definition of road as being anything that you can drive on, whether it be private or not. I know people that say they got in trouble for using them in the woods in Rangeley so now they can't use them anywhere except thier driveway. The only time they aren't illegal to use, as I understood it, is if you have them serving as your fog lights.
