Miniature light bulbs and battery. Wire-ended miniature incandescent light bulbs connected to the terminals of a zinc-carbon battery. Unlike larger incandescent bulbs, these ones are connected to their power supply with wires. These bulbs are similar in size to an LED (light-emitting diode), but unlike LEDs produce light by passing electricity through a metal filament that heats up and glows.
