I'd like to preface this with a warning - my boat is very dirty, I need to give it some love! I have it in my garage, which is apparantly pretty dusty/dirty.
I spent some time in the garage and installed these into my cup holders. It was super easy, and they look awesome. I wired them to turn on with the courtesy lights, which is how I have the rest of my LED's wired as well.
This is what they look like in place, not turned on.
