pedal reflectors are now really cheaply made and fragile. I need to track some decent ones down for my commuter. I have lost 2 of the 4 reflectors. I think pedal reflectors are really good at letting people know there is a bike there -- if they show up. I have seen people riding where the only reason I saw them was their pedal reflectors. But you have to be looking, because many if not most people pedal with their heels down much of the time. So they only show up part of the time. An ankle band is much more effective 100% of the time.
