light bulb
Edison's bright invention
A light bulb is a glass enclosure containing a filament or gas that produces light when electricity passes through it.
The bulb screws or clips into a socket.
Since its invention, the light bulb has become a symbol for ideas and inspiration—a light bulb appearing over someone's head in cartoons signals a sudden insight: A light bulb went off and I knew exactly what to do.
