This is: a lightbulb.
Most people connect these up to some source of electricity, like an outlet, or a lamp plugged into an outlet, or a potatoe. They are then usually used to light up something, like a living room, or a closet. This particular lightbulb belonged to Josef Von Standen. He was a lightbulb sniper during the blitz. A lightbulb sniper's job was to find and destroy any lightbulb that was on during an air raid by any menas neccicary - including, but not limited to, sniper rifles. This particular lightbulb sat above his dining room table until its unfortunate death.
