I’ll say right up front that I’ve never really understood the need for a flashing headlight on a bike. Isn’t the point of a headlight to be able to see where you’re going? I finally decided that cyclists must use them as another way to be visible to motorists and others.
But last night, I had an interesting experience. I was on Allen Blvd. in Beaverton, driving east on my way home from the Safeway. There was a cyclist on Allen (a very brave soul indeed to ride on a very busy street with no bike lanes, no shoulder, and fairly narrow travel lanes). He was also going east. When I passed him, he took the lane behind me.
He had a blindingly bright flashing headlight. Unfortunately, it was aimed high enough than when I checked my mirror, I got that bright flash right in my eyes.
