Credit Card Lightbulb

Here's a really cool product I found when I was surfing the net. It is a credit card sized lightbulb which can fight in your wallet. I think it is a really great idea because it makes searching through your wallet in the dark that much easier when you have a little lightbulb in there. By flipping the lightbulb up you turn it on but when it is flush with the frame it is off and can fit nicely in your wallet. It's something which is a really cool idea but If I had one I
don't think I would really use it that often. Here's a link for some more info on it:
