Hi all, I'm looking for a circuit, either a kit, or built that will flash
low wattage 12 volt lamps AT RANDOM. I need to flash about 25
bayonet bulbs a bunch at a time but completely random. Like if I just
used old style flashing bulbs with the bi-matalic strip inside.
Also it would need the capability to change speed.
Does anything like this exist without spending a lot of money??

THANKS!!
