10mm RGB self cycling LED-About 50 centsThe LED I have is a 10mm RGB self cycling LED. I bought these from Ebay (Top Bright)but you should be able to find else where. You have to make sure they are self cycling LEDs. This means the LEDs with cycle through all of the colors by them selves with out having to have an additional controller.
