If you're the guy that rides around with those super bright anti aircraft headlights on your truck go ahead and put them on low beam and break the switch. May need to unplug one of them while you're at it. Had one of those behind me the other night and even with my lights on bright my truck was casting a shadow in front of me. The other vehicle was at least 60 or 70 yards back. It looked like a shadow in the light from a welder.
