I've got a flag for stylin'.
I also have front and rear lights on the helmet, four red lights on the rear of the trike, two red lights for side fill in on the steering bars, headlight up front on flash during the day. Three of the rear reds at mounted on the holder for my HiVis Slow Driver sign.
I notice that drivers tend to give me a good wide berth. I assume they think it is some poor handicapper in his chair and they will lose points for getting me. I want to be flashing and blinking like a major police stop.
Overkill? Does it work? Sometimes. Last time I Shared the Road, I woke up in intensive care to discover that I had a neurosurgeon, an eye surgeon, a neurologist and a plain ole' MD attending me. There must be a reason I like bike trails.
