The Pocket Light is not only slim enough to fit in your pocket, it can fit into your wallet. Designed by Hyun Jin Yoon & Eun Hak Lee, it’s the size of a credit card and powered by a small cell. When you need a quick light, just take it out and flip up the lightbulb cut out. Currently it looks like it’s just a concept but it’s definitely a do-able one that could and should be in production soon.
