You are right and the price is too. I wonder if anyone can see it in daylight?
I usually use motorcycle stuff--it can definitely be seen in daylight.
I prefer LEDs, so I've converted the incandescent stuff to that for the most part, with aquarium lighting in some (cuz it's already water-resistant). Teh signals on teh trike are still incandescent, but they are still clearly daylight visible.
Aside from that, I also put mine up where they are at least at regular car-driver eye-level, or higher, so they *have* to be seen by car drivers, and are unlikely to be missed even by SUV/truck drivers.
Also, a little square with arrows is much less likely to be instantly and unequivocally understood by drivers than simple blinking lights to one side of the bike or the other. People are trained to look for what you see on a car--so if you emulate that the communication is instantaneous and universal.
Anything that doesn't emulate that isn't universal, and requires the person seeing it to think first and figure it out. Even though ti might not take very long, it is still a conscious process, and takes longer than a trained-in unthinking reaction.
Even if they don't *use* turn signals, people still know what they mean.
(same with brake lights, except those are automatically activated in cars/etc., so they don't have to "use" them).
