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
