ELI5: How do outdoor holiday lights not short out or cause a fire. I see outdoor decorations plugged into extension cords and they are exposed to the elements such as rain and snow.

Typically both the outdoor extension cord and the exterior outlet will have a fuse or ground fault interruptor to kill the power if there’s a short.

Of course, people do rig improper shit up all the time and burn their houses down with holiday decorations.
