I was picking up some stuff at my local Radio Shack today and on the clearence table was a whole bucket full of tiny light bulbs. They are $0.25 each and are really small and have about 4 or 6 inch wire leads coming off of them. I was told they are 12 volt. I am not nor have I ever been in the market for lights this small so I have no idea if this is a good deal or not. If this is a deal and you want some just let me know. I remember reading a post or two about lighting up guages. If someone wants a picture of the one I picked up and can post it for me I'll email it to you.
