Rolled home LATE from work last night, and since NO ONE was in front of me, as I was driving across Rosamond Dry Lake, I got to playing with my HIGHs. If you momentarily move the turn signal arm forward for HIGHs and immediately move the arm back to neutral, it turns the Auto-High-Beams ON and OFF. Left them on, on the way home, they came ON/OFF at more appropriate times. They did turn OFF at one point, for no apparent reason, and right back ON again. I observed that the BRIGHT LED traffic lights, with no street lamps nearby, would trigger the HIGHs to automatically turn OFF.
