Lighting Circuit Wiring Diagram Multiple Lights. All the light wiring diagrams are available in the old and the new cable colours to avoid confusion. Here the source is at the first switch sw1 and 3 wire cable runs from there to the first light l1.
Every 120 volt circuit that powers lights in a typical home has two conducting wires and a ground. If you need to know how to wire a two way switch then this is the place to start. The hot and neutral terminals on each fixture are spliced with a pigtail to the circuit wires which then continue on to the next light.

Extending to three or more lights. If you need to know how to wire a two way switch then this is the place to start. As with the other lighting diagrams in this section the first ceiling rose could be a junction box instead or could be connected via the loop at switch method. In this circuit two light fixtures are shown but more can be added by duplicating the wiring arrangement between the fixtures for each additional light.
