After teasing the possability of new music, Harry Styles dropped a brand new single Friday called "Lights Up."

Leading up to the song's release, the singer placed mysterious posters across New York City and London that read "DO YOU KNOW WHO YOU ARE?"

"What do you mean? I’m sorry by the way, I’m never coming back down," the singer begins as the music video pans to him standing in the ocean flooded by a red light.

Styles also rides around on the back of a motorcycle and dances in a hazy club in the clip.

"Shine, Step into the light, It’s so bright sometimes, I’m not ever going back," The former One Direction artist repeats in the melodic chorus.

Styles' song and music video invoke a strong 70's rock vibe, proving that the singer is distancing himself from his former pop persona.

"Lights Up" will be featured in Styles' sophomore solo album, which is still yet to be named.

While it's unknown exactly when the album will come out, the singer has launched a new website DYKWYA -- which stands for Do You Know Who You Are -- that personally compliments fans by name. Fans have taken this as a sign that the album is coming very soon.

Also, it comes with phrases like "Treat People With Kindness," -- a fitting message to coincide with the week of National Mental Health Day.
