Reversing 8 Lamp Light Chaser/sequencer

I want to build a Reversing 8 lamp(230v , 100W lamps) Chaser. Does anyone have any schematics for this functionality?

By 'reversing' i mean, Once the sequence reaches the 8th lamp from the 1st lamp to the 8th. The sequence should start from 8th and goes back till the 1st lamp

Just cascade two counters and "OR" the lamp drivers with a diode network.

Are you "Allgäuer"?

Can you provide the Circuit diagram?
