Anyone else see these? Just curious what any of you thought. As a newbie I still don't feel 100% confidant about removing my hands from the bars to signal. I know I NEED to, but end up doing so quickly and I know I could do a better job.

Are they gimmicky or would they really work? They appear pretty bright in the video even during the day.
