light bulbs
Edison's bright invention
Light bulbs are glass enclosures containing a filament or gas that produces light when electricity passes through.
The technology has evolved from incandescent bulbs, which glow by heating a wire filament, to fluorescent and LED bulbs.
Figuratively, a light bulb represents a sudden idea or realization: A light bulb went off in my head.
