@metaltao In the phrase "light out" the word "light" is being used as a verb to remove the light from a source like a lantern or candle (which in retrospect seems kind of counter-intuitive, but it's actually just because it's a warped version of "turn out the lights"). In the phrase "lights out", it is often a shortened version of "knocking someone's lights out", as in knocking someone out. Though "lights out" can be used with the former meaning of "light out", so I don't know if I'd say the two have completely different meanings as much as one possess specific connotations unique from the other.
