Reelight battery free bike light, a Kickstarter project review

Groningen is the city of bikes and for most of these bikes the lights don't work. Reelight recently did a Kickstart project for a battery free bike light system. I ordered it and installed it this week. Here is a quick review of the Reelight CIO battery free bike light.

TL;DR
The concept is nice, but I think it could be improvement even futher.

The light should have a sensor so it detects daylight and disables the flashing (Reelight says it chooses not to do so, because of a 19% decrease in daylight bike accidents, but I would prefer a beam at night which is even safer). It could than charge a small battery pack during the day.
With that power it could have a beam of light for very dark area’s during the night which would make the light even better.
Reelight should use better metals so installation becomes easier and more robust.

If they make those improves the light might be worth the €59,- they retail for.
