As a result of a combination of an obscured view from my the mouth guard of my full-face helmet, my tank bag, and my priority of watching out for cagers and looking where I'm going; I either can't see or don't look at my dash. I, for some reason, am forever forgetting to cancel my turn signals. I know one of these days I'm going to forget, and leave them on, and someone is going to pull out in front of me.
Here is a quick video clip (12s) of their operation:
They look way too bright in the video, but in fact they are perfect for night use, or maybe 10% too bright. If located in your peripheral vision, they're actually not bad AT ALL. On cloudy days you will notice them, but not on bright sunny days, particularly with the sun shining right through them. If you happen to go through a bit of shade, even on a bright day you also will notice them.
My next version will have a switch for day/night settings with an additional set brighter LEDs for daylight use. I used a spare 4-pin computer plug at my seat (you won't knock your bike over if you walk away with it still plugged in - only a few pounds of force to uncouple) with a wire running inside my jacket. A pair of RCA jacks plugging from the jacket wire to the helmet keep you safe from clotheslining yourself should the worst happen.
