This is not a wallet bank card or any other card, but is a pocket Lighting, conceptually designed by designer Hyun Jin Yoon & Eun Hak Lee. The light-bulb shaped powered by a small cell and turns on by just a simple flip of the switch. But I’m not sure how long the cell can be last for.
I believe most of you have impromptu experience with mobile phone light for searching in the dark. This Mobile Pocket Light perhaps provides a whole new light.
