This song is about him saying as beautiful and gorgeous the girl is, he wants to love her for who she really is and genuinely love her for her personality not just for her looks because that's not the kind of person that he's trying to come across as. As a result ,he loves her so much that he wants to express his love to her in a unique way that people don't tend to express them selves in." I wanna love you with the lights on" as opposed to loving her with the lights off like most people tend to do but this girl is so special that he feels that she needs to be treated specially as well. PS-I'm 13 just so you know
