Quote from Swimming Pool Lighting :
After that you can choose the pool lights that you want to use as replacement like the bulbs but you should turn off all electrical systems which operate in or around the swimming pool. Therefore you can use the electrical test meter to make sure the circuits are truly dead before you enter the water. Wearing your underwater goggles is important. Using screwdriver to remove the screw at the top of the pool light lens is the next thing you have to do. After that you can perform a visual inspection of the wiring.
