How do you separate lights on the same switch

If the fixtures are wired in a series – meaning the switch connects only to one cable and the fixtures are wired to each other inside the wall – an electrician will have to be called to separate the cables and run them individually to the switch. …

Run your cable from the first light to the second light. Connect the black wire from the switch to the black wire from the first light and the black wire coming from the second light. Attach the white from the second light to the white from the power supply.
