Yeah, that reflection almost got me crushed once. I was in a bike lane which makes all of the traffic ahead appear to be giving right turn signals. One day an old 1970s SUV was actually giving a right turn signal and whatever brain cell is responsible for "seeing" that just assumed it was my headlight reflection. Added to that the sun was positioned directly over the roof of the car in the late afternoon making it hard to see in the first place. The tail light from that era were tiny and maybe they also had a short in the wiring. Anyway, I would have sworn it was a no-signal right-hook until I got home and watched the video.

Here is the vid. The incident I mentioned is the second one in the video.

Otherwise the daytime flashing headlight has made a huge difference in my safety. I think many motorists assume I am a cop or something because crossing traffic literally freeze like the proverbial "deer in headlights". I also use a Dinotti flashing tail light that can be seen from outer space even during daylight hours. The Dinotti is my answer to overtaking cars with distracted (on the phone) motorists. Both lights have been very effective.
