To wire a light without a neutral, you'll need to use a switch loop. Begin by running a cable from the light fixture to the switch location. Connect the hot wire from the circuit to one of the terminals on the switch, and then connect the wire leading to the fixture to the other terminal. At the fixture, connect this wire to the hot terminal. Remember, the neutral wire at the fixture connects directly to the neutral from the power supply. Always ensure to follow local electrical codes and consider consulting a professional.
