Some models of black table lamps have the light bulb inside the lamp. When illuminated, the lamp emits a soft light that is the color of the glass body enclosing the bulb. These lamps use the same wiring as a traditional lamp with the socket on top. The bulbs and wiring sets inside a lamp require the removal of the bottom and unscrew the wiring bracket assembly and the installation of a new socket. If a vintage lamp needs to rewire the best it is to replace the plug and wiring at the same time.
Unplug the lamp from the electrical outlet. Remove the small screws on the bottom of the lamp and remove the bottom part of the metal ring. Slide a small flat screwdriver under the edge of the cardboard circle and the lamp takes off. Remove the screw in the bulb holder bracket. Pull the wiring installation of the lamp from the bottom of the black table lamps. Cut the wiring from the bottom with a pliers leaving approximately 3 inches below the lamp wiring assembly. Unscrew the bulb and keep it in reserve. Place a small flat-blade screwdriver on the screw of the tube set lamp. Turn the screw counterclockwise to loosen it.

Pull the old wiring out of the screws and discard it. Push the new lamp wiring through the lower lamp nipple and slide the cap onto the top of the loose end of the wiring. Place the loose end of the wiring on a piece of cardboard on top of a table. Cut a slit between the two wires in the crack starting about 8 inches from the end. Strip about 1/2 inch of insulation from the end of each individual wire.
