How to Connect the Red Wire for a Ceiling Light Fixture
- The Red Wire
The red wire is most likely a spare wire that was intended to be used when wiring for a ceiling fan.
- The Wall Switch
Typically when a ceiling fan is installed the red wire is most commonly used for the light and the black is commonly for the fan motor.
- The Red Wire as a Spare Wire
When a ceiling fan is not installed, this spare red wire is insulated with electrical tape or capped off with a wire nut.
