Mine had the very slightest amound of moisture inside and looking at the pin contacts they were slightly oxidized. Moving the bulb in or out a few times seemed to clean them right upI wonder it if would be worth it to check the existing light for corrosion around the bulb contacts.

Oh, and turbo1ton there are 8 bulbs needed. Only 1 or 2 operate at the same time.
Been there, done that.. Luckily I have some dive gear and will pull it out if I need to do some work in the pool for some extended time. Usually its just one screw to take the fixture out of the niche. I think they designed it to be able to remove in the amount of time most people can hold their breath.Ok was not sure and did not want to have to remove the light again if I found out latter it was required as installing light fixture after pulling it out was not easy. As the niche is several feet below the water line I had to put on a diving mask to see clearly and then sink down 3 feet into the water. The water then keep pushing me back up before I could get it aligned enough in the niche to start the top mounting screw. Is there and easier way of installing the light?
You need a weight belt and a buoyancy compensator (BC-air vest). The weights keep you down, the BC allows you to adjust your buoyancy and compensate for how deep you are.It not so much that I can not hold my breath lo g enough ( though I was able to hold it much longer when younger) but staying down under as I keep being pushed up above the fixture. I guess I will see if I can borrow a divers weight belt or wear a pair of swim trucks or shorts with pockets and put rocks in the pockets. Thanks for your help.
When I have light fixtures out to replace bulbs do I need to do any maintenance of the niche like epoxying the area where the light cable comes thruough the pool wall? I think i might have read somewhere about putting pool putty around it?
