Call a pro for a leaking pool light.

You likely need a new gasket, but water + electricity is not a DIY moment.

A pool light leak almost always comes from a dried-out or cracked gasket around the lens or the cord. Replacing that gasket is straightforward if you already know how to pull the light niche, drain the water from behind it, and properly seal everything back up. That’s a lot of ifs.

The bigger issue: you’re messing with 120V (or 12V) in a wet environment. Even with the breaker off, moisture can create hidden shorts. One wrong move with the wrong screwdriver or a pinched wire, and you’ve got a bigger problem than a leak. Most pool light repairs require a special pot of sealant, torque specs on the screws, and a thorough inspection of the cord’s rubber boot. It’s not a “tighten it and hope” job.

I fix plenty of things myself, but pool lights are the exception. Call an electrician who works on pools, or a pool service company. They have the tools and the insurance.

This is not where you save $150.
