Instructables

I read about a 2-pin RGB LED that alternates between colors?

Not sure if they exist, but I'm interested in buying a few if they do.  Supposedly the controller circuitry is in the LED package itself and alternates between colors every couple of seconds.  Does this exist?

sure do!

Ebay is my favourite to search for leds cheap and quick from china:

arbitrary store I found searching for "rgb led"
--one unique thing about search terms you'll find 'rgb led slow' or 'rgb led fast' which usually indicates what the internal chip will do with the leds,
