Where can I find some small, cheap flashing lights? It doesn't really matter what kind of light they are as long as they flash, a variety of colors would be nice but not necessary, the ability to turn them on and off is nice but not necessary, they shouldn't require a cumbersome power source but they don't need to last much longer than ten minutes, and I need to be able to obtain them by tomorrow (Saturday) in NYC.

I tried to look up LED levels on the inter-web but all I found was scientific mumbo jumbo, can someone just tell me which one to buy please!? Thanks
