I have a new halogen light to replace the old bathroom light?
My new halogen bathroom light set (a gluster of 3) has a Live Neutral and earth wires. However the old bathroom light has 3 black wires 2 of which are wired together into one side of the fitting and one wired on oits own into the other side. How do I know what wire goes where?
