The easiest way would probably be to use a microprocessor with enough outputs to accomodate all the lights and just program it so that the lights alternate the way you described.

Otherwise, there are timer chips you can find that output square waves. If you had a timer for each led, and found a way to generate a delay between the different timers you might be able to do the same thing. This would be more involved though.

Paul, just kidding from here.. But have to say it.

Does it make you feel old he had no idea that was what he wanted?

And thinks to himself KEWL (assuming a him), KITT, I like the extra T..

But it is funny, most of us here know the show?

David H. is still on TV here in the States with a new modern day GONG show.
