“Lights Up” is Harry Styles' first single of 2019, featuring harmonious vocals and melancholy lyrics. The song marks Harry’s first release since his eponymous May 2017 album, Harry Styles.

The track’s release coincided with National Coming Out Day. It was accompanied by a music video, which features Harry surrounded by scantily-clad men and women. Styles was relatively tight-lipped about the track leading up to its debut, only posting the artwork on Instagram hours before the drop; his first post in over a year.
