Tom if you stand far enough back and turn the turn signal on you are not going to be able to distinguish what the heck it's doing because the signals are located to close to each other, their not spaced apart like a motorcycle or a car; this spacing problem has been the subject of other similar lights, like those on helmets, that is completely unnoticeable. This need for a turn signal has never ever been something that I, nor my friends that I have spoken about this sort of thing over the years, could see any advantage. We all simply have used hand signals and no one has ever been in danger because of it, and not I after 40 years of riding either.
