Turn Off the Light, Vol. 1 is the second extended play by German singer-songwriter Kim Petras. It was released on 1 October 2018 through her own label, BunHead. Petras began promoting the EP in mid-September, posting heavily edited photos to Instagram of herself, according to Paper, "styled as a sexy dead Victoria's Secret angel/Hades side-chick/goth middle schooler's notebook-doodled fantasy. She later posted to Twitter that she "[couldn't] wait to share" a collaboration with Elvira. Three vinyl LP pressings were released on 20 September 2019: a "pink and white galaxy swirl" and a clear vinyl, which were exclusive to Urban Outfitters in the US, and a neon pink pressing which is a general retail release. The songs from the EP were incorporated into the full-length follow-up Turn Off the Light, which was released as her second mixtape one year later on 1 October 2019.
