Just thought of this last night when faced with a nimwit with his brights on...
We need to find someone here who works for a defense contractor on missle guidance systems - develop an automatic sensor that will detect brights either from the front or rear and can fire a guided paint pellet gun. Fill the pellets with a translucent paint that will dim the lights on impact but not cover them completely and walla! Instant and perminant light dimming!!
