Great stuff. It's more than a simple gimmick. I could actually see people adopting to use CLARA. There are signal lights that can e used for bikes. But the problem is they tend to be small and less noticeable. CLARA takes car of that problem. You can remain visible in poor light conditions. The light can lasts 8 hours (16 hours in strobe mode).
Small Suggestion
I'd like to see more colors for these lights and maybe for the vests too.
