Learn how to Wire A Ceiling Light Red Wire
Wiring color codes are standardized in North America. Black wires always signify the positive, or hot, leg of the present, while white wires signify negative, also called neutral or return. Ground wires are either left bare or covered with green insulation. When there is an extra hot wire, it’s red. Ceiling fixtures almost always have a black and white wire. In rare instances, the kit may include a red and yellow wire instead. In this case, red is hot. An additional red wire within the electrical box is probably an additional hot wire for a fan.
Things You will Need
3 wire caps
Metal-boring drill bit
Red Wire within the Electrical switch pulse return line Box
Test the wires within the ceiling box with a voltage tester. If there may be an extra red wire, you need to get a reading of 120 volts whenever you touch the terminals of the tester to the red and white wires. It must be identical to the measurement while you touch the ends of the black and white wires with the voltage tester.
Turn off the power to the circuit, either by flipping a switch or turning off the breaker in the primary panel that controls the circuit. Check the wires again with the voltage tester to verify that there is no such thing as a voltage reading.
Twist a wire cap onto the red wire, then push it into the box. Make sure that no metal shows outside the cap when it’s fully tightened.
Use pliers to twist the black wire from the house circuit clockwise together with the black wire of the sunshine. When they are secure, twist on a wire cap. Repeat this process with the white wires. The light may have a bare ground wire or one covered in green insulation. Twist it together with the bare wire from the house circuit, then screw on a wire cap.
Push the wires into the electrical box. Mount the light fixture with the included hardware.
Red Wire on the sunshine Fixture
Turn off the power to the light circuit, then check the wires with a voltage tester to verify there isn’t any voltage reading.
Twist the red wire from the sunshine fixture together with the black wire from the house circuit with pliers. Cap the wires.

The right way to Ground a Ceiling Light
Twist the white wire from the house circuit together with the white or yellow wire from the sunshine, and cap them. If there may be a third wire, it will likely be either bare, green or blue. Twist it along with the bare wire from the house circuit. If there isn’t any third wire, ground the fixture by attaching the bare wire to the metal base of the fixture. You’ll have to install a ground screw.
Drill a hole slightly smaller than the diameter of a green ground screw in the metal base of the fixture. Screw in the ground screw. Wrap the bottom wire around it, then tighten the screw.
Tips & Warnings
Some low voltage lights have various colored wires, some of which are used for dimming. Consult the instructions that came with the light for the right wire connections.
If the electrical box was previously used for a fan, the wall switch is probably a two-pole switch. Either disconnect the red wire from the switch or replace the switch with a single-pole version.
Ensure the circuit power is off before you make any electrical connections. You may receive a shock otherwise. If you’re standing on a ladder at the time, the shock may cause you to fall.
