Did you all know that a list of web links is copyrightable? While an individual link might not be, the effort to put together a unique collection of links is a copyrigtable piece of work. So if you can copyright a list of links, I find it reasonable to say that a collection of lights as a collection are a copyrightable effort. Placing one light at dial location X with values A, B, and C is probably not copyrightable, but placing THIRTY lights in a set of 10 or 20 and collecting them seems like just as much a creative act as making a list of web links.
