@kingston; Thanks for the video. That help clear up my lack of understanding from your previous post. I've seen the rear flashers on motorcycles before but I've never seen the headlight version till now.

Videos usually can't demonstrate the effects of flashing lights as seen in the real world so people need to understand that the motorcycle headlight ( in the video ) in the real world would have looked much brighter. Regardless, the video did an excellent job of showing the effect of an on-coming flashing light vs. a steady light. Summing up, if it works for the motorcyclist it will work for us. Of course not too many cyclists are going to run out and start using a bright flashing headlamp during the day.

That might be because most cyclist don't use lights in the day...and when they do they usually aren't that bright. I've noticed the lights on cyclist before without actually knowing it was a cyclist ( during the day ) but it is extremely rare. Usually when this happens the cyclist is using a very bright ( flashing ) rear light or flashing front light and is a good distance away. I generally don't use a flashing light when riding in full daylight but if I'm riding down a road with a lot of shade I might use the front flasher.
