making a little lamp in Unity?

Hey everyone, i know i can use self illuminating shaders to make stuff glow but since i've made my dashboard i want to have a couple of little tiny blinking red lamps.

is this possible in unity free?

Thanks..

Just script a change to the shader to "turn on" and "turn off".
