I have seen a few messages regarding this topic but I am very new to this and I want to be sure i get it right. What I am doing is installing 4 can lights with the switch at the end of the run. I am familiar with wiring just one light but I am still unclear on multiple lights. Can someone explain the wiring on the lights and pretend you are talking to a third grader. After you explain it, I should be able to figure it out but will they be wired in series or parallel. Thanks!!
