Thanks for your reply!
The rope lighting surrounds the perimeter of our pool, maybe a foot above the water, within a track that runs just above the tracking for our automatic cover . There's a large box sitting in a landscaped area that controls the lights. Somebody had told me once that there's a part in that box that we should try replacing first, but I've lost my notes on what he said it was. We also have small light spots in our concrete that light up where a person needs to step up or down. This is also tied into the rope lighting and that box. I'm confused on how these get replaced because they dimmed along with the rope lighting. Would a contractor put all these spot lights in when there's no way to ever replace them once they dim???
