Hi, I currently have 2 LED battens installed in the garage and would like to add an extra one in the middle of them. All cables are accessible even though they are in a conduit. Both lights run off a single switch and looking at the connections inside, both live wires are connected to the 2 terminals of the switch and the 2 neutral wires a connected together by a piece of choc block connector and both earths connected to the metal back box. Any advice please in installing the additional light?
