More lights can be added to this circuit by duplicating the wiring shown here for each additional fixture. This drawing shows the wiring for multiple lights in a 4 way switch circuit with the source and fixtures coming before the switches. At SW1 the red and white wires from the 3-wire cable running between the switches function as the travelers with the white marked for hot using black tape or paint. At each light it's connected to the neutral terminal with a pigtail and at the last light, directly to the fixture neutral. The white wire is marked with black tape and spliced to the black wire running to the common terminal on SW2.īack at the lights the source neutral is connected to the neutral terminal on L1 and spliced with the white wire running to the next fixture. The source hot is spliced to the black wire running between the lights and at the last light it is spliced to the black wire running through to the common on SW1, it does not connect to the light fixtures. As with the other diagrams on this page, more lights can be added by duplicating the wiring arrangement between the fixtures.Ī 3-wire cable runs from L1 to L2 and 2-wire cable runs from there to the first switch. Here the source and the fixtures come before the switches. This diagram illustrates another multiple light circuit controlled by 3 way switches. The white traveler wire is wrapped with black tape to mark it as hot They don't connect to the light fixtures at any point. The travelers are run between the lights using the second cable black and white wires and at the last light, they are spliced to continue on to the traveler terminals on SW2. If more lights are added, this wire would be spliced to the fixture and to the white wire running to the next light. At L2 this white wire connects directly to the neutral terminal on the light fixture. It is also spliced with the white wire running to the second light, L2. The neutral is spliced to the white cable wire running to the lights and then spliced with a pigtail to the neutral terminal at L1. Two, 2-wire cables run between each light fixture after that and 3-wire cable runs from the last light to SW2.Īt the beginning of the circuit the hot source is connected to the common terminal on SW1. Here the source is at the first switch, SW1, and 3-wire cable runs from there to the first light, L1. 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.

The diagrams on this page illustrate connecting multiple lights in 3 way and 4 way switch circuits.
