A light bulb transforms electrical energy into light, featuring an illumination source encased in a clear outer shell.

Similar to how a flashlight operates on batteries, you can link a battery to a compact light fixture or bulb to illuminate it. Follow the steps provided to discover how to create a battery-powered light bulb.
Required Items:
- Size D battery
- Two insulated wire pieces
- A small light bulb or compact light fixture
- Tape (preferably electrical tape, though any type will suffice)
Steps to follow:
- Remove ½ to 1 inch (1.5 to 2.5 centimeters) of insulation from both ends of each wire [source: Dave].
- Attach one end of the first wire to the battery's negative terminal using tape. Secure the other end to the side of the light bulb's stem [source: Energy Kids].
- Connect one end of the second wire to the battery's positive terminal with tape. Fasten the other end to the base of the light bulb's stem. Once both wires are connected, the bulb will illuminate [source: Dave]. Electrons travel from the battery's negative terminal, through the bulb, and return to the positive terminal, causing the bulb to light up [source: Energy Kids].
Exercise caution when dealing with exposed wires. A small electric current flows through them, so handle them carefully [source: Electropaedia].
