When you replace a light bulb in your pool light fixture, you should have 4'-5' of extra cord behind your light fixture to be able to set your light fixture up on the pool deck. Sometimes the fight fixture is installed without this extra 4'-5' and the cord is not long enough to reach the pool deck. This guide shows your how to temporarily extend your light cord an extra 4'-5' on the light fixture side.
DISCONNECT LIGHT WIRES - Locate the power junction box for your lights. It will normally be next to the house close to the pool control box. Open up the junction box and disconnect the wires to your light . You may have several light cables coming into this box. Generally they are labeled on the PVC pipes. If not, you may have to disconnect each indepentently and turn the power back on and off to see which cabel powers each light. Mark the pipes for the future.
ATTACH CORD TO WIRES - Now you want to attach a cord or special fish tape to the light wires. One way to do this is to bend back the white and black wires to form a loop. Leave the green ground wire out straight. Then attach the cord though the loop. The green ground wire will parallel the cord as shown.
PULL WIRES ON LIGHT END - Pull the light fixture away from the wall. Once it is off the wall, reach behind the fixture and pull the wire out of the wall behind the fixture. Avoid pulling the wire out of the wall by pulling on the fixture. It may break the sealed connection at the back of the fixture. Pull out enough wire to be able to set the light fixture on the pool deck.
PULL WIRE BACK TO TERMINAL BOX - After you have replace the light bulb, lower the light fixture into the water and pull the light cable back into the pipe by pulling on the cord at the terminal box end of the cable. Have someone feed the cable into the pipe at the back of the pool niche so that it doesn't bind as you are pulling on the other end.
