Hi
Wonder if anyone can help. My MIL has a ceiling light that when connected it does not switch off. We have changed the wall switch. There are 4 wires coming from the light socket 2 x red, 2 x black. Into the wall socket are 1 x red and 1 x black. If we only put 2 of the black and red into the ceiling socket, the other light in the room does not go on. The other light has a blue and a brown wire going into it. Can anyone help please?
