Credit card-sized pocket light fits in your wallet

While it won't magnify the fine print on your cardholder agreement, this credit card-sized pocket light could nevertheless make your day just a little brighter.

Designed by Hyun Jin Yoon and Eun Hak Lee, this pocket light is "about the size of a credit card and powered by a small cell," writes Web magazine Yanko Design, which introduced the wallet-ready innovation. "Flip up the lightbulb shaped cut-out to switch on the soft, mellow, glow of bliss."

I have to admit it's a very cool idea. Think of all the times having a light in your wallet could prove helpful: finding items that fall on the floor of a darkened car, setting the romantic mood lighting on a candle-less dinner table, lighting the way to your kitchen for a midnight snack, helping you read the playbill in a darkened theater, etc.

How many other uses for a credit card-sized pocket light can you come up with?
