Quote from Swimming Pool Lighting :
Change the light bulb. If you want to change the entire fixture, you should first unwire the old one and wire it again the new pool light in its place. A good seal around the light fixture to prevent water can get into the light is important when you replace the lens gasket. Coil it into bundle, slide it to the back, slide the light fixture back to place and screw it into the wall, then you can set the ground fault circuit interrupter and turn the electrical system back on and you can try the lights immediately.
