When choosing a light bulb, find one that is around 15-25 volts so a single battery can power them. To simplify the wire attachment process, use a battery snap with wires pre-attached and a 9-volt battery or battery pack.

If you don’t have wire strippers, you can carefully use scissors to cut off the insulation. Be careful not to cut all the way through the wire.

Alternatively, if you are using a battery snap, snap the end onto the end of a 9-volt battery or the battery pack. Use caution while building your circuit. Although unlikely, it is possible to get a very small shock if you touch the wire directly while attached to the battery. You can avoid this by only touching the insulated part of the wire or removing the batteries until you install the light bulb.

Light bulbs can heat up quickly so be careful when installing and removing the bulb. If the bulb doesn’t light, check to make sure the wires are touching the ends of the battery and in contact with the metal of the screws.

Make sure screws are tightened down to maintain contact. In some cases, you may need to strip more of the insulation off the wire.
