Drag racing "christmas tree" lite sequencer circuit?

A drag racing "Christmas Tree" flashes six (6) lites in sequence to initiate a race. The rate should be adjustable and no programable eproms please. The lites should flash "on" then "off" only once with a reset switch to start again. Just a plain simple adjustable timer circuit that a middle school student could understand and use.

Does anyone knows how to build such light sequencer circuit board or where to get one?  I would like to build a mini version of a drag racing X-mas tree (like but using small LED's or actual X-mas lights.  Anyone?

Let me know
