Add some colour to your projects with these auto-cycling rainbow LEDs. Each 5 mm LED automatically cycles through every hue of the rainbow at three different speeds — fast, medium, and slow — one after the other, with no external controller or library required. Just supply power and enjoy the show.

From the outside, these LEDs look and behave just like standard single-colour 5 mm LEDs, making them a drop-in replacement in any circuit where you want colour-changing effects without additional complexity.
