I dunno, I wouldn't use em for my only source of signaling. I'd rather have them in the rear and in front, so I'm guaranteed to be seen. Though, those would supplement a good blinker kit rather nicely.
But they would work if you installed them on the high performance throttlegrips, not stock unfortunately.
well, the switch is integrated into the grips, so using the components to build something else might not be easier than just using turn signals designed for motorcycles/mopeds.
