Swimming in a pool has never been better, especially when you add some underwater pool lights to it.

In this article, we will guide you on how to install underwater pool lights in your pool.

Tools and Materials Needed

2. Screwdriver

3. Electrical tape

4. Waterproof connectors

6. Wire nuts

Step 1: Preparation

The first step is to switch off the power that supplies electricity to the pool. You can do this from your circuit breaker box. It's also essential to make sure that the pool's power is switched off.

Step 2: Drain Water

To install the pool lights, you will need some space to work, so you will have to drain some water from the pool to reach the area you want to work on. You can use a submersible pump to drain the water.

Step 3: Remove old lights

If you have old pool lights or fixtures, you will have to remove them before installing new ones. If you have screws, unscrew the old lights and remove them. If they are sealed with silicone, you can use a putty knife to remove it.

Step 4: Install new lights

Now that you have removed the old lights, you can install the new LED underwater pool lights. Follow the manufacturer's instructions on how to install them. Most LED lights have a bracket that attaches them to the side of the pool.

Step 5: Connect the wires

Once the lights are in place, it's time to connect the wires. You can use waterproof connectors to stop water from getting into the electrical connections. Strip the wires and connect them according to the manufacturer's instructions.

Step 6: Test the lights

Now that you have connected the wires, it's time to test the lights. Turn the power back on and see if the lights are working correctly. If there are any issues, switch off the power and check the connections.

Step 7: Cover the backplate

After testing the lights, make sure to cover the backplate with silicone to protect the electrical connections from water.

Step 8: Refill the pool

Finally, it's time to refill the pool with the water you drained. Wait until the pool is full to switch on the lights.


Overall, installing underwater pool lights is a simple and fun process. With the right tools and materials, you can have them up and running in no time. Not only are they fun to look at, but they also add a level of safety to your pool at night. Use these instructions as a guide to help you install your pool lights without any difficulty.
