So it looks like my pool light was left on all winter and the bulb is now burnt out. I've never changed the bulb before, so before I start unscrewing things I wanted to run a few things by you guys. This light is a circular light that's about 2 feet below the surface and is cut into the liner. There looks to be a wide trim ring around the outside with 6 or 8 screws and then there are two other screws, one on top and one on the bottom that have holes cut in the trim ring so you can access them, but they're underneath it...if that makes sense.
Which screws do I want to take out to just remove the bulb? Is there any possibility of me causing a massive leak here?
