"Lights" follows Glacier's previous Detroit techno-inspired single "Bond Girl". The track, co-produced with Take A Daytrip, was the first release since her 2025 debut album, with "Lights" offering the second preview of Glacier's next musical chapter.

Produced by Kwes Darko, the track sees Glacier explore the experience of having to be "always on" while in the spotlight. It's described as her most "upfront and accessible" work yet, expanding on her club-inspired approach with a piece built on driving synths and bells.
