Credit Card Lightbulb
If you ever find yourself unexpectedly in the dark, you can either light your way with your cell phone or just whip out this cool new Credit Card Lightbulb. This super thin, credit card-sized lightbulb folds flat and fits in your wallet. To use, just push the little bulb vertical and it lights up, while the rest of the card serves as a stand. Handy little gadget and cheap too!
