LED is DC, and it needs regulated DC.
LED stands for Light Emitting Diode. So they can be fed AC and illuminate. One way of making a tri-colour LED is to connect a red and a green one in anti-parallel within the same package. Result DC one way red, DC the other way green, AC yellow (actually the illusion of yellow due to presistance of vision).
