Becky G dropped this song on her official YouTube page on December 23, 2015. She explained its meaning: "The Lights' is a true example of when I say 'Music is how I express myself.' I wrote this song because I had bottled up things I was feeling and didn't know what else to do other than put it into my work in the studio that day. Writing this helped me a lot. It's not a hype song but it's a song that means a lot to me."
