Then you'd be back to this inferior dynamo lighting which goes out at

Where are the tragic tales of cyclists who are seriously injured or
killed because their dynamo standlights were too dim or too short-lived?
Somehow those tales have failed to make it into the safety literature!


As we all know reports of fatal car-cyclist collisions are notoriously
short on details.

You claim to be something like a "teacher for safe cycling" yet you
don't know or ignore the most basic safety precautions. Astounding.
Actually, sad.

Unless their is a case-controlled, double-blind, study, Frank won't
believe that increasing visibility at night, both for seeing and being
seen, is beneficial.

Following that to its logical conclusion, he should be opposed to any
lighting at all. Or at least he should be able to provide a chart of
accidents versus lumens to prove that there is no benefit to a cyclist
improving his or her conspicuity and his or her ability to see the road
and off to the sides.

Yet there are numerous studies that have been cited in this group that
do prove the benefits of better conspicuity.


The topper was a car driver. It was foggy and she was tearing down a
freeway. One passenger said "That's dangerous to drive so fast here, you
can barely see!" ... "Oh, that's ok. Because the others won't see much
either".
