To wire a light switch to a light, you will need to connect the switch to the power source and the light fixture. Turn off the power, remove the cover plate, and disconnect the existing switch. Connect the wires from the switch to the corresponding wires in the wall and the light fixture. Secure the connections with wire nuts and screw the switch back into place. Turn the power back on and test the switch to ensure it is working properly.
