I plan on adding 3 or 4 more can lights in my kitchen. Currently there are 5 lights on the circuit I want to add to. The current lights are controlled by 3 separate switches. I was planning on just tapping into one of the current lights and daisy chaining off of it to add the lights. However I don't know where the power comes in at, switch or light. Does this make a difference? I plan on having a buddy that knows more about wiring than I do to help but thought I'd check with INGO experts as well.
