Took 5 lights from “Ozium” I think it’s called. Drilled 5 holes for the lights in a piece of aluminum, the lights have a small ring around the base which Is wider than the rest. Made a bracket from aluminum and clear coated it. The swim platform has a small tab I was able to drill 4 bolts to to bolt up the bracket to. Also put some silicone along the back of each of the lights to the bracket. Pretty simple and way cheaper than buying the name brand stuff for $$$ and no hull drilling. Had it on all summer so far and still works great no issues. Pics are at lake of the Ozarks.
