In Theatre speak, LIGHTS ON! means turning on the spotlight and focusing on the stage for the world to see the actors acting their parts. House lights are dimmed in order to draw attention to the stage.       "Dark to Light" referrences the house lights being darkened (in shadow) and the turning on of the spot light, to lure the eyes to the object(s) that are "illuminated."       So, as Q has pointed out in the past, "Dark to Light" turns on the spotlight, "Lights On" points to the stage setting and the actors responsible.      My 20 yr old asked me if Q might have been an actor or someone familiar with stage acting, because he keyed in on those two particular phrases first. That's what started his Quest down the Rabbit Hole.
