You have two wiring arrangement options for connecting multiple lights: series and parallel. The circuit diagrams below show a simple setup for wiring multiple lights to one switch on a circuit with two lights in series and parallel.. Wiring multiple lights to a single light switch is similar to the basic light switch configuration with the additional light bulbs attached to the first one as shown in the diagram.
The ground wire should also be connected together in this manner, but to the ground terminal on the switch. Each light will have a cable "entering" (from the switch) and "exiting" (away from the switch). At each light you'll connect the entering and exiting black wires together, as well as 1 terminal on the light. Do the same with the white wires.. Learn how to wire two lights to one switch with a detailed wiring diagram. Step-by-step instructions and diagrams to help you complete the wiring project with ease.
