I had the same problem turning off the headlights by accident.
It is kinda frequent... whenever I'm on a mountain road, I get flashed as if I had brights on. When I go to show them what REAL brights look like, I make an idiot of myself by spinning the knob to off position while trying to yank it back to flash them. Its a stupid design. If there is a fix, I would love to know about it.
