nodding I see what you are saying, bagginsbill. But I suspect that in some of those really old light sets that it was simply that they forgot to turn a light on in their set or forgot to delete the light all together. Maybe the creators of those light sets intended to do as you just explained and didn't put that in their readme. Of course, some of the lights I still have in P4 (practically fossils), did not come with readme files.
