I found a link on reddit for battery led pool lights and had to buy and try them. These run on 3 AA batteries, are waterproof a have rgb functions. They came as a 4 pack. I am blown away by how bright they are. https://www.amazon.com/gp/aw/d/B08S6K4QQ1/ref=ya_aw_od_pi?ie=UTF8&psc=1
UPDATE: So far they've been in the pool 8 weeks or so, still working properly, was having trouble with the remote, but changed out the coin battery and was back in business.
