In the past, SE has dubbed "good lights" in Omen campaigns to mean that when you start an omen floor, the objectives are already "good" (I guess this means, the objectives are completed? or you are able to go to the next Omen floor without completing primary objectives?). My guess is that the ROE means that first "good light" is what took place. *shrug*
I think the "good lights" just refer to the good "omen" numbers you get when you port up. It doesn't have anything to do with "The light shall come even if you refuse to obey" message and subsequent free floor. I don't have a list of "good" numbers, but I have noticed that same-triple digit Omen numbers produce the treasure portent floor (which the Double Light Up Campaign helps boost, you get two chances at treasure floor vs just one). I.e. 222, 777 etc is a "good" omen number. You will see a treasure floor after killing the floor 3 boss or any of the 5 normal bosses.
