It's Christmas time, so today I take a look at vintage Zlatokov fairy lights that were quite popular in 1970's and 1980's in Czechoslovakia. I managed to repair them in this video. Being made donkey's years ago, those obviously contain classic tungsten lamps, not LEDs. I really prefer the soft incandescent light inside a big lampshade over the very sharp monochromatic colors of LEDs. I also took a look at a newer set of tungsten lamps and explained what is an antifuse.
WARNING: Some types of Christmas lights are not isolated from the mains and they contain dangerous mains voltage. Risk of electric shock and death. Risk of fire.
