I have three outdoor wall mounted lights, the one furthest from the front door has the PIR. This light also has the wires from the indoor switch to it and one other black wire. The other two lights have one set of wires L,N,E to them and operate with the PIR light is triggered. I now want to change the light with the PIR to the one nearst the door. How can I acheive this? All the wiring is enclosed in the walls.
