I have this same SuperBright Led strip affixed to my golf cart and am very happy with them-they are, super Bright! you can see me coming a mile away. BUT.....on my boat I've got something more elegant. I keep them up year round, waterproof, RBG, completely encased in flexible soft clear plastic.
I got mine from a marine supplier, they're made for boats. Mine have a remote, are programmable but not dimmable.
