Pool lights

[SunnyOptimism]

I don't close my pool because of location so take my opinion with a grain of salt. I don't see why you'd have to remove the light from the niche unless you were seriously worried about a deep freeze. I don't a thing about Michigan winters but if you've got 6-8" if water above the light and you deep freeze down to that level then that may warrant the effort.

By the way, aren't lights designed to float when removed from their niches?

Here in the Chicago area, many people I know with mesh-covers, "float" their regular lights to protect them from the freeze-thaw-rain-freeze cycle. Dropping them has an advantage in that you "clean" the light niches that way, but it sounds like your housing is difficult. I don't know anything about LED lights. Personally, I would rather deal with a difficult removal than a costly replacement. 0.02$
