Was on an urban group ride a couple years ago, and near the end of it, it was getting dark, so several of us flipped on lights. One guy had an absolute FLAMETHROWER, and aimed it back at the group to watch them all try a small stunt that would otherwise not gave been a challenge. Two guys tried it, one nearly wiped out, but the growing chorus of complaints did little to make Light Boy to relocate.

Making drivers cower, however, can be 'fun'; thirty years ago, I had a real 'redneck rig', a pickup with a light bar across the top. One night, driving across town, lights normal, nothing on 'bright', another driver started flashing his brights at me. I flashed back, just to show that my brights weren't on, but he continued flashing. SOOOOOOOOOOOOOOOOO, I flipped the brights back on, AND hit the toggles for the light bar. All of the sudden, it was NOONTIME out, and the guy QUICKLY shut down his activity, and drove on.
