Incandescent Lamp Flasher Here is a lamp flashing device, not sure of the period but I am guessing the 1960s as I had one like it back then. It has a bimetallic strip heated by a coil of wire through which the lamp is connected. The current at switch-on is insufficient to light the lamp, but when the heating element warms up, the switch operates and the lamp lights. After a couple of seconds, the heater cools and the lamp switches off. The lamp then continues to flash at a rate of approximately two seconds on and two seconds off. It will only work satisfactorily with lamps of between 40 and 60W at 200-250V. If anyone has any idea of who made this and where, it would be very much appreciated. Keywords: Miscellaneous

A nice but simple way to switch a lamp on and off. Bulb Man

I remember that we used that in the form of a plug adapter for our Christmas lights when I was a kid. Simple but effective.

The Christmas lights we had used a special bulb with some sort of flashing control in it, I presume a bimetallic strip. It worked because the lights were connected in series.
