Well, if you're going to make light-up garments, this is one way to do it. Hamburg company, Realflex, has created a product that not only lights up for safety, but warms up the rider as well. They developed the product through their new product think tank called be8lich. There are a ton of light-up bike jackets and accessories to make cyclists visible. This low-tech version doesn't require batteries and it acts as leg warmers too. If anyone tries this product out, I'm curious to know what they think. Watch the (rather entertaining) video for more info:
