How to Rewire a LampBuying an old lamp at a flea market, garage sale or antique store is fun. If the lamp does not work because of faulty, broken or missing wiring, do not despair or walk away from a bargain. Perhaps you can get a discount from the buyer. Just tell the seller you "could use it as a nick-nack."If a favorite lamp stops working because of worn or broken wiring, you do not need to throw it away. Re-wire the lamp and have a functional piece of furniture just like new. Antique lamps can be rewired with minimal effort.At the local DIY store, purchase a new lamp cord, and if needed, a new socket with or without a harp for lampshades. For antique or older lamps, take the old one with you to see if a new socket will work with the existing harp assembly. It should, as lightbulb sizes have not changed much over the years.Remove the harp and the socket assembly. Remove the wiring from the socket with a screwdriver and needle nose pliers. Thread the new wire through the lamp and split the wire into two wires for about 3 inches. Tie a gentle knot in the cords to prevent the cord pulling out. Attach the wires, hot to the brass screw and neutral to the silver. Attach the socket assembly and the harp. Insert a light bulb and turn the lamp on.
