Light Socket Wiring Diagram. This diagram illustrates wiring for one switch to control 2 or more lights. The second socket b typically holds a small low wattage bulb similar to a night light bulb.
The threaded socket is the neutral. The cable that comes from the switch to the light has a black and a red wire both of these are live wires. This is not always the case.

Third connect the black hot wire from the 3 way switch to the hot smooth not ribbed wire of the incoming lamp cord and the black hot wire from the main center socket. For regulations governing heights of sockets etc please see our socket height diy project. This diagram illustrates the wiring for a bedside lamp with two sockets. Finally connect all remaining wires which will include the ribbed side neutral wire of the incoming lamp cord all the white neutral cords from the 3 side arm sockets.
