I used the waterproof submersible led lights from Menards Worked great for the first year. The second year I noticed some of the leds were out and opened them up. the housing is not waterproof but everything inside looks like it's supposed to be encased in a clear rubber gel-like layer but I noticed a bunch of the little leads were sticking out of it and heavily corroded I cleaned them up and used liquid electrical tape and has been good ever sense.
