What does "love me lights out" mean in Beyoncé's song XO?

Here's part of the lyrics: In the darkest night hour (In the darkest night hour) I'll search through the crowd (I'll search through the crowd) Your face is all that I see I'll give you everything Baby love me lights out Baby love me lights out You can turn my lights out I'm also a lil bit confused with the last part "You can turn my lights out." I really like the song, it's written by Ryan Tedder, one of my favorite song writers. I really appreciate any help and thanks in advance.
