 1 Locate the circuit breaker for the lamp holder and turn the switch off. Circuit breakers are in your home's main electrical panel and should be labeled by room. If the breaker isn't labeled, turn the light on and turn each breaker off until the light goes out.Turn off the circuit breaker or remove the fuse from the fuse box that controls the light fixture.

 2 Position the ladder beneath the recessed lighting and have a helper hold the ladder while you climb.

3 Unscrew the light bulb and test the lamp holderfor electrical current with a multimeter. Turn the multimeter selector switch to 250 ACV (alternating current voltage), touch the red wire lead to the metal tab in the center of the lamp holderand the black wire to the metal threaded side.Remove the glass cover over the light you are working on. The cover typically either slides off or unscrews, if it's a round cover.

 4 Unscrew and remove the lightbulb, then take out the two screws in the ceramic lamp holder on each side of the bulb holder.Remove the two mounting screws on each side of the lamp holderbase by turning them counterclockwise with a screwdriver. Pull the lamp holderfixture gently -- it will now be free of the electrical box and suspended by two electrical wires screwed into the lamp socket fixture base. Make note of the wire colors and their placement on the fixture. Wires are usually black (hot) and white (neutral)

 5 Pull down on the lamp holderand turn it to the side to expose the wiring. Loosen the two screws in the side of the fixture to pull off the two wires. Make a note of which wire attaches to which terminal screw.

 6 Wrap the new wires around the screw posts on the new porcelain lamp holder and tighten each with the screwdriver.Touch one multimeter wire lead (red or black) to one of the lamp holderwire screws and the other lead to the metal tab in the center of the socket. If there is a maximum reading, the wire you are testing is the hot wire. If no reading is present, repeat the procedure, but touch the lead to the remaining wire screw. You should now have a maximum reading and will be sure of which wire is the hot wire.
