This is a telling response, IMHO, in that it illustrates the problem with any lighting. When the PBSF came out, it lit up the night! Now it's only good enough to be a secondary light. What's attention-grabbing this year will be leftover trash in two years.

And yet, I keep seeing more and more people wearing high-vis lime or orange. It used to be only road construction flag persons; now the guys driving mechanical garbage trucks wear them -- much less every cop who gets out of his car at an accident. If you're really worried about being seen in the day, loud clothing is being used by more people who are only intermittently on the streets, and practically everyone who spends any serious time in the roads. Could it be the high-vis green or orange jersey or jacket is good enough for a cyclist?
