I have a large basement with 10 can lights in the ceiling controlled by a single pull switch at the bottom of the stairs. I have framed in a bedroom that essentially cuts the area in half with 6 of the 10 lights being inside the new room. I wish to keep 4 on the original switch while bypassing the series with a switch inside the bedroom to control the 6 bedroom cans.
Is there a way to do so using the existing wiring? Or am I stuck running all new wire to some or all of the lights?
