I just watched a TikTok about how people used to plug in things to their light sockets when electricity was first becoming popular. And they kept calling the plug a light socket, what rule says it’s not a plug that screws in? And why shouldn’t plugs screw in? We have material science to make plugs and cables hard enough that if you kick the wire it still doesn’t come out. Electrical connections should be more secure. That’s all I’m saying.
They exist and have done pretty much since the screw in light socket (ES) was invented.
