How To Fix A Pool Light

How To Fix A Pool Light, Swimming pools are a fantastic asset, and their aesthetic can be significantly enhanced by a well-lit pool at night. However, like any other feature, pool lights can malfunction. This guide will walk you through the process of identifying issues with your pool light and safely fixing them.

Introduction to Pool Light Troubleshooting

Before diving into repairs, it’s important to understand why pool lights are essential and how they function. They’re not just for ambiance; they’re a crucial safety feature for night swimmers.

Importance of Proper Pool Lighting

Proper pool lighting ensures that swimmers can see obstacles, including other people, in and around the pool, reducing the risk of accidents. It also adds to the overall appeal and ambiance of your pool and backyard area.

Identifying Common Pool Light Issues

Several issues could be at play if your pool light isn’t working correctly. Here are a few possible culprits:

Burned Out Bulbs

Like any light, a pool light bulb has a finite lifespan. It’s one of the most common issues you might encounter.

Faulty Wiring

Over time, wiring can degrade, especially in outdoor environments. Corroded, damaged, or loose wires can interrupt power to your pool light.

Water Intrusion

Pool lights are designed to be water-resistant, but if the seal protecting your light fixture from water is broken, it can cause multiple issues, including shorts in the electrical system.

Safety First: Precautions Before You Start

Before beginning any repair, it’s crucial to prioritize safety. Ensure the power supply is off, and consider wearing rubber gloves to minimize the risk of electric shock.

How To Fix A Pool Light (Step-by-Step Guide)

A shimmering pool light not only elevates the ambiance of your pool area after sunset but also ensures safety by illuminating the water. However, like all electrical components, pool lights can encounter issues, and knowing how to fix them yourself can save both time and money. Now, let’s dive into the nitty-gritty of fixing that light.

Step 1: Gather Necessary Tools

You’ll need screwdrivers, a voltage tester, silicone sealant, and possibly a replacement bulb or wiring.

Step 2: Turn Off the Power

This step is crucial: turn off the power to your pool lights at the circuit breaker before starting any work.

Step 3: Remove the Light Fixture

Typically, pool lights are secured by screws or a locking mechanism. Remove these to pull the light fixture out of the niche.

Step 4: Inspect and Diagnose

Check for obvious signs of damage, such as water inside the fixture, frayed wires, or a shattered bulb. A voltage tester can help determine if the fixture is receiving power.

Step 5: Execute the Fix

Depending on the issue, this might involve replacing the bulb, repairing or replacing wires, or resealing the light fixture to prevent water intrusion.

Step 6: Reinstall the Light Fixture

After addressing the issue, reinstall the light fixture in the niche, ensuring it’s securely fastened and the seal is tight.

When To Call A Professional

If you’re uncomfortable with these repairs, or if the problem seems complex, don’t hesitate to call a professional. Electricity and water are a dangerous combination.

Maintaining Your Pool Light

Proper maintenance can prevent future issues.

Regular Cleaning

Keep the light fixture clean of algae and mineral build-up, which can cause premature degradation.

Routine Inspections

Regularly check for signs of wear and tear, especially in the wiring and seals.


Pool light maintenance and repair don’t have to be daunting tasks. With safety precautions and the right tools, you can ensure your pool remains a safe, enjoyable space for night-time swimming. Remember, when in doubt, professional electricians are there for a reason!

Frequently Asked Questions (FAQs)

Can LED pool lights be replaced or repaired?

LED pool lights can be replaced, and sometimes repaired, depending on the issue. However, LED lights tend to have a longer lifespan than traditional bulbs.

How often should I inspect my pool lights?

It’s a good practice to inspect your pool lights at least once before the swimming pool season begins and once it ends.

Is it safe to repair a pool light on my own?

If you follow safety protocols, such as turning off power at the breaker and using a voltage tester, minor repairs can be safely undertaken. For more complex issues, hire a professional.

Do pool lights use a lot of electricity?

It depends on the type of light. LED lights are energy-efficient and cost less to operate compared to traditional incandescent or halogen bulbs.

Can a pool light electrocute you?

There’s a risk if the light isn’t properly sealed or the wiring is faulty, which is why precautions like shutting off power and routine inspections are vital. Always prioritize safety and call a professional if unsure.

Can you replace a pool light underwater?

you can replace a pool light underwater, and in fact, it’s designed for an underwater replacement to avoid having to drain your pool. First, ensure the electricity is turned off at the circuit breaker for safety. Then, you can remove the light fixture from its niche in the pool wall while you’re in the water.

Once removed, bring the fixture up to the pool deck (the fixture should have enough cord to allow this), where you can dry it off and perform the necessary bulb replacement or other repairs. Once done, you can replace the fixture in its niche, all without draining the pool. Always prioritize safety, and if you’re unsure, consult a professional.

Why do pool lights stop working?

Pool lights can stop working for a few common reasons. The simplest issue could be a burned-out bulb, just like any other light.

However, there are other potential causes, including water intrusion due to a compromised fixture seal, which can lead to other electrical issues or even short out the bulb. Faulty wiring, often due to corrosion or wear and tear over time, can also cause power failures to the light. Regular maintenance and inspections can help identify and prevent these issues, ensuring your pool light’s longevity.

How do pool lights work?

Pool lights work similarly to regular lights but with extra protection to safely operate underwater. They are housed in water-tight fixtures to prevent water from reaching the electrical components. These fixtures sit in niches built into the pool wall, keeping them flush with the lining to prevent any obstruction for swimmers.

Pool lights can be traditional incandescent bulbs, though many modern pools use LED lights for their energy efficiency and longer lifespan. They are connected to the property’s electrical circuit and can be switched on and off just like the lights in your home, usually from a switch located somewhere convenient outside the pool. Always remember, due to the combination of electricity and water, pool lights should be installed, maintained, and repaired with a strong emphasis on safety.
