How to Repair an Inground Pool Light
- 1). Turn the breaker off, and ensure that the light switch is turned off.
- 2). Reach your hand into the water, and remove the stainless screw at the top portion of the light.
- 3). Remove the light fixture from the niche by hand, or with a flat head screwdriver. Some pools have a small tab at the bottom of the fixture to help you pop the fixture out. Bring the fixture to the pool surface and onto the deck.
- 4). Place the fixture on a towel and dismantle the unit by removing the screws or undoing the tabs, depending upon your lighting model. Discard of a broken lens, if applicable.
- 5). Cover the bulb with a washrag, and remove the bulb by twisting counter-clockwise. If you have a halogen lamp, you may need to push downward as you twist the bulb out. Dispose of the damaged bulb.
- 6). Clean and dry-out the inside of the fixture with a dry cloth. Check for any crumbling or rusting parts --- such as screws --- and replace as necessary.
- 7). Install the new pool bulb in the fixture unit; only use bulbs specifically intended to work inside your pool.
- 8). Test the new bulb by turning on the breaker, then flipping the switch on the light for 1 to 2 seconds to ensure the light works. Never operate a pool light out of the water for more than 1 to 2 seconds; the light needs the water around it to keep it from overheating. Turn the breaker off again.
- 9). Install a new lens, if necessary, or replace the undamaged lens back into the fixture. Reassemble the fixture, by installing a new rubber lens gasket in the same position as the old one. Don't reuse an old gasket; the seal won't be tight enough.

Check for a good gasket seal by placing the unit in the water. You may notice a few bubbles coming from the ring; however if you see streaming bubbles you'll need to pull it out, re-screw it and check again for air leaks. - 11
Replace the unit in the pool, making sure to coil the long cords inside the cavity. Ensure that the light is lined up correctly, with the flat-head screw at the 12 o'clock position, and the tab near the bottom. Secure the screw until it is snug, but not too tight. - 12
Retest the light again by turning on the breaker and flipping the switch.
