Change Your Pool’s Lighting Fixture with Advice from an Expert Electrician in Trumbull, CT

In-water pool lights are not a requirement for your backyard pool, but adding a few sure does make it look nice—and as a bonus, you can see better in the water when it’s dark out! Once you get used to having pool lights, you’ll find enjoyment in relaxing nighttime swimming sessions. Even sitting poolside with the pool lights on is a calming experience. But, like most electrical devices, your pool lights, lighting fixtures and hardware will eventually need replacing. How often depends on your pool’s water chemistry, and maybe even the climate you live in.

Here’s some helpful advice from an expert electrician in Trumbull, CT—basic steps to safely change your pool’s lights or lighting fixtures.


Before diving into the process of changing a light, first get a replacement bulb and new hardware. To ensure the right replacement piece, take the burned-out bulb with you to get a new one to perfectly match the socket and protective cover. And since the combination of water and electricity can cause electrocution, pay close attention to the following safety steps. If you’re not comfortable doing it yourself, hire a professional electrician in Trumbull, CT:

  • Step 1: Switch off all electricity leading to the swimming pool area from the circuit breaker. You can use a circuit tester to ensure all power is off.
  • Step 2: Unscrew the screw holding the pool light housing unit to the pool’s side. Slide a flat screwdriver between the pool wall and light casing to free the light housing.
  • Step 3: Be gentle with the clamp screw and remove the gasket and lens. There will likely be six or more screws holding these pieces in place. Check for corrosion as you remove the screws and seek the right replacements.
  • Step 4: Wipe the inside of the casing of any splashed water; use a towel to pull the old bulb from the housing unit. Use a clean, dry towel or cloth to hold the replacement bulb to screw it into place.
  • Step 5: After the new light bulb is in and the gasket set up, change the pool lens. Get the screws back in to secure the lens in place. Now, check for air leaks by submerging the housing in the water. Bubbles mean the housing is not properly sealed.
  • Step 6: The pool light’s power cord needs to be rolled around the back of the lighting fixture, then put the housing back in place, fixing it to the side of the pool with the first screw you removed.
  • Step 7: Reestablish power from the circuit breaker to your swimming pool, check that all the replaced lights are working and get back to enjoying swim time!
