How to Replace a Pool Light Bulb: 1 Minute to Replace Your Pool Light Bulb and Enjoy Night SwimmingSarah ThompsonJan 19, 2026Table of ContentsTips 1FAQFree Smart Home PlannerAI-Powered smart home design software 2025Home Design for FreeReplacing a pool light bulb might sound daunting, but with the right method, you can tackle it safely and efficiently. Pool lights are designed to be serviced from inside the pool, but most can be accessed without lowering the water level. Start by turning off all power to the pool from the circuit breaker to ensure safety. Next, use a screwdriver to remove the single screw at the top of the pool light fixture bezel (usually located at the 12 o’clock position). Gently pry the fixture away from its niche using a flathead screwdriver—there is typically enough cord to rest the fixture on the pool deck. Remove the fixture's cover and replace the old bulb with a compatible, waterproof swimming pool bulb. Always double-check the bulb’s wattage and type for your specific fixture. Reassemble the unit, making sure the gasket is in good condition to prevent leaks. Test the light on deck before placing it back. Once confirmed, coil the extra cord and reposition the fixture back into its niche, securing the screw tightly.Tips 1:As an interior designer, I find the lighting ambiance of a pool area makes a significant impact.
