How to make a blinker?

Hello. I'm trying to make a blinker (a particle which can turn on and turn off after 1 second).

I don't know if it is possible to "turn on" a light "inside" the particle an then "turn off".

The only thing that I have thought is change the color of the particle, but I want something more realistic.

Thank you.

partial help

Of course you have seen the controller call schedule....
And check out Transparency.tz in demos/graphics.

Ok. Thanks! I will work with it.

I would like something to change the light of the object, not only the color... but with the combination of trasparency and color will be nice.
