Make A Battery Operated Light

Lights are very simple electrical components and represent an ideal beginner direct current (DC) project. While household lighting involves powerful, high-amperage electricity, battery-operated lights are easy and relatively safe to build, even for a novice. With just a few simple tools and basic wiring knowledge, you can easily build a battery-operated light.

Instructions

Build a Battery-operated Light

1. Strip 1/4-inch of insulation from each end of each length of wire. Using wire strippers, carefully strip away 1/4-inch of insulation from each end of the two lengths of wire. Use caution not to break or damage the exposed wire.

2. Connect the light socket to the two lengths of wire. The socket should have two protruding leads, likely colored red and black (these leads should have 1/4-inch of exposed, uninsulated wire; if they do not, use the wire strippers to strip 1/4-inch of insulation from the end of each wire). Connect the exposed end of one length of wire to the exposed end of the red wire, and secure the connection using electrical tape or solder. Repeat this process for the black lead.

3. Connect the two lengths of wire to the battery enclosure. Like the light socket, the battery enclosure should have two protruding wires, one red and one black. If no bare wiring protrudes, use wire strippers to remove approximately 1/4-inch of insulation from each battery enclosure lead. Connect the exposed end of the red enclosure wire to the exposed end of the wire connected to the red lead from the light socket using electrical tape or solder. Repeat this process for the black lead and the wire connected to the black lead from the socket.

4. Screw the light bulb into the light bulb socket. Insert the threaded end of the light bulb into the socket, and twist the bulb clockwise until it is firmly seated in the socket.

5. Insert batteries into the enclosure, using care to ensure the negative (flat) end of the battery presses against the spring portion of the enclosure. When all batteries are installed, the light should illuminate.

6. If necessary, troubleshoot wiring connections. If the light bulb fails to light, verify that all wiring connections are secure and that no stray insulation is impeding the flow of electricity. If the light bulb still does not light, replace the batteries with newer ones.
