# Pool light

A pool light is a waterproof fixture mounted in the pool wall that lights the water for night swimming and safety.

A working pool light makes evening swims safer and shows you the water at night. Most pool lights sit in a wall niche and plug into a power source through a sealed cord.

Signs of trouble: a light that flickers, stays dark, or trips the breaker, and water inside the lens. Water in the fixture means a failed seal. Turn the light off and do not touch it. Light repair involves electricity, so call a qualified pro.
