Continuous pulse on/off

[hotrodjohn71]

Hi group. I have a 110v electrical item that i want the ability to turn on and off about every half second continuously.

There isn't much current draw at all. It's an old Christmas bells decoration.

What would you suggest for a pulse on/off unit I can plug my setup into that would cycle 110v AC?

Thank you

You can buy a flasher bulb that you can plug into the first lamp and it will, after 5 to 10 seconds, start flashing the whole strand. It uses a bimetallic strip and, once hot, will start flashing faster.
