As far as my wife knows the pool light has never been replaced since the pool was installed fifty years ago. The light burned out four or five years ago but I thought I would have to empty the pool to fix it until I saw the thread here on replacing the bulb. My light has no screw holding it in place, instead there is a spring clip at the top. When I got the fixture out and apart I saw that there was water inside. The bulb was toast as there were pieces of filament loose in the bulb. My concern is the condition of the socket after sitting in water for a long time. Should I replace the socket?
