Also, check all seals to make sure that it is water-tight. You can do this by submerging the light pool light in shallow water and check if there are bubbles coming off.

Step 3: Set-Up Power Supply

Once you have assembled the lights, you need to set up the power supply. Battery-operated light simply needs their batteries installed. If you have a corded light, you need to set up a power source. Locate the GFCI outlet that is the closest to your pool and that the light cord can reach. Mount the light transformer to the wall next to the outlet and plug the pool light in.

Most submersible lights are batter and solar-powered so there is no need for any wiring. All that you need to do is to attach the battery to the pool light, turn it on, and drop it in the pool until it is fully submerged in water.

Take note that the housing design of the pool light will determine if you can remove it from the pool without disconnecting any wiring. Below are the steps that you can follow to safely replace the pool light.

Turn Off Circuit Breaker

The first thing that you need to do is to turn off the circuit breaker of the swimming pool light. To do this step safely, you can place a non-contact voltage tester against the wall switch of the swimming pool light. The tester will serve as a warning if there is a presence of electricity by flashing and beeping. Next, turn on the switch and double-check for the presence of electricity. Once you have made sure that there is no electricity, turn the switch back off.

Open the Pool Light Housing

The next thing that you need to do is to open the pool light housing. To do this, you need to look for a single screw along the bottom of the pool light housing bezel. You might need to enter the pool to access the screw if you cannot reach it from outside the pool. Next, remove the screw from the housing.

Remove the Pool Housing

The next step is to remove the pool light housing from the side of the pool. Usually, the pool light housing features a long and waterproof cord that is attached to it which makes it possible to replace the light from outside the water. Remove the housing pool light and place it outside the pool.

Check and Repair Any Damage to the Housing

Check behind the bezel for the brass screw that holds the bezel, light housing gasket, and lens to the housing. Next, loosen the screws to release the bezel, gasket, and lens. Make sure to remove any screws that are damaged or corroded and replace them with new ones. Do not forget to inspect the gasket if there are any wear, cracks, or crimps and make the necessary repair and replacement.

Replace the Light Bulb

Make sure that you dry the housing with a towel to get rid of any moisture. Next, remove the original light bulb by untwisting it from the housing socket. Use a replacement bulb with the same shape, size, and wattage as the original bulb. Next, screw the replacement bulb in place.

Install New Light Housing

If applicable, you can install the new light housing gasket around the edge of the light lens. Next, place the lens on the end of the housing and install the bezel over it. Make sure that you securely tighten the screws that hold the bezel to the pool light housing.

Insert Housing into the Pool

The next step that you need to do is to place the housing cord around the housing and insert the housing into the pool light opening. Check if there is a steady stream of air bubbles that escapes from the housing once you have submerged it in the water. See to it that you properly remove and replace the bezel, gasket, and lens to make sure that the pool light is tightly sealed and protected against water seepage.
