I tried the replacement lights from Amazon but they leaked and let water into the light which didn't end well so they went back. Perhaps I got a bad set but both lights leaked, if it was just one I'd say it was bad luck but both made me wonder about the quality.
I've done my own using these lights (

I'll get some photos later if that'll help.
