Rube Goldberg machine?

Possibly, but needs to flash for 5 minutes!

Entry criteria:
You can use any size or voltage of incandescent bulb.

The flash rate must be between 0.5Hz and 2Hz. The mark-space ratio is unimportant but the difference between the bulb being on and off must be clearly visible.

The flashing must be done electrically (i.e. causing the filament in the bulb to glow on and off). A bulb that is on continuously but has shutters, lenses etc. moving in front of it is not an eligible entry.

Your system doesn’t have to have amazing longevity but it must be able to run for at least 5 minutes without breaking down, exploding etc.

Newton’s cradle with the end balls completing/breaking the circuit when they touch/leave the rest of the stack?

Could have an electro-magnet turning on/off to pull the balls back and forth
