A friend of mine who was a state trooper said they would stop people who flashed their lights and ask them if something was wrong with their headlights. Then he would ask for license and registration, go back to his car and wait a few minutes, then let the "flasher" go. It wasnt against the law to flash the lights, but if they got caught, their own trip would be delayed...
BTW saw a motorcycle cop this AM on Morse, hidden back in one of the neighborhood entrances. Did I flash to oncoming folks? Nah....
