Wow, that looks really cool. There are an assortment of battery-powered lights available on Taobao. I see a lot of people with lights on the spokes of their wheels which look cool when you’re cycling around, or rear-facing lights on the seat post. Nothing as cool as the Halo Belt that I’ve seen, though.
Are you contributing to this Kickstarter? It looks like the 300 yuan contribution will get you one shipped to Chengdu, which should arrive in July.
