I've read the topics on flashing vs. steady lights, but my question is even more basic:
Is there any data to support my contention that a flashing rear light will significantly increase the safety of a rider in the DAY time? I know as an automobile driver I certainly see them sooner, but that's purely anecdotal.
My 14-yr-old, raised on a cul-de-sac with what I would call a "less than stellar" sense of urban traffic, naturally thinks blinky lights on the back of your bike make you a loser. But while he is a teenager, he's smart and logical enough that if I had some convincing data on accident rates, he'd probably buy it.
Try as I might, I've been unable to find much!
