actually in PA. you can drive at night, as long as you have all lights working. that was a very old stipulation, as model T's didn't have headlights.
im in PA also and am registered as antique, and I drive it whenever I feel like it. unless your passing the same cop everyday, and he notices your tags, whos gonna know??? oh and never paying registration, or dealing with inspections or emissions ever again is a nice plus.
