Danger, sometimes yes. I've had close calls but not terribly close.
However, like many other risks that can be reduced with lights so I use
lights. Never had a close call with the MagicShine clones. They see me
much better.

And I've never had that close call with even a 2.4 Watt halogen light powered
by a standard dynamo. I don't need them to see me better. They see me fine,
according to my decades of riding experience.

Again, riding home after teaching a night class, I had motorists up ahead of
me wait over 20 seconds for me to pass before they either turned left or pulled
out of a side street. I _never_ had any indication a motorist did not see
my headlight.

I realize I live in an area so safe there aren't even any mountain lions. And
I never heard of a death around here caused by a lack of sunglasses. But I
still don't believe Joerg's area is the death pit he pretends.

I believe from my own experiences that a flashing light does attract
attention better then a steady light, and tests by various highway
agencies seems to show the same thing. I believe I've told the story
about the guy with the bright orange knee socks who passed me on a
straight section of road and nearly a kilometer away you could still
see those orange legs going up and down, up and down :-)


I used to have a battery powered flashing headlight for urban bicycle
warfare .. ahem .. riding.

When I swapped to a dynamo powered steady headlight I had fewer SMIDSY
incidents. Not zero, but certainly fewer.
