Thanks for all the comments. I'm starting to be convinced, and now I think one main reason it can be more effective than hi-viz is that to see a hi-viz cyclist, the driver has to be looking in that direction; OTOH, you don't have to be looking toward a light source in order to see its light, esp. flashing light. The light "comes at you" actively, while hi-viz is passively waiting to be seen. With that said, lights do have great directional restraint which hi-viz is less subject to. Also, in many case you can see a neon lime figure far away when lights are still too far to be seen.

Really?
