Continuous pulse on/off

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.
 
Hi, Just to let you folks know. I am 85 yrs old and at this stage only have a rom memory. Still very much interested in electronics and it, The result is that i still read as much as possible and remember for the moment. So if i am not very active(or not at all) i very much enjoy all the posts. Have a nice christmas and a good new year.
Greetings

If you can tolerate a 1 second on and 1 second off interval, a timer such as this should work.

How well It works depends upon the current of the load it is in series with.
