How to Replace Lights for Hot Tubs

Like pools, spas have lights that allow you to use them at night and illuminate the water so you can actually see what you're doing. Like all lights, the spa lights will eventually burn out. Replacing the spa lights restores the nighttime illumination to your spa. However, in order to replace the lights you have to drain your spa so you can access the lights.

  1. Drain the spa. Open the drain valve on the spa and allow the water to drain completely.

  2. Wipe off the light cover and the area around the cover with the towel.

  3. Twist the light cover from the spa. It will be either plastic or glass and should unscrew so you can access the light bulb inside of it.

  4. Unscrew the light bulb from the housing inside the spa's light fixture. Screw a new light bulb in the light socket. Make sure the new bulb is the same make as the original bulb.

  5. Screw the light cover back on the light and make sure it is tight so no water can seep inside of it. Turn on the light to test it. If it works, fill the spa with water.
