I used a Lightman xenon strobe on my bike for a long time. The amber lens makes for an incredibly visible warning light. I was under the impression that these were more compliant with the law than a red flasher, but now that I checked the CVC, I can't find anything permitting rear lights for slow moving vehicles or bicycles. Fooey on legislators and bureaucrats.
Anyone have a lightman and a DiNotte and a RadBot to compare the three?
