In an interview with Billboard, Rogers revealed that the song was about "feeling out of control".

Meredith Nardino of Atwood Magazine said that "...Rogers is laying her whole heart on the table, bringing us backstage to some of the most challenging moments of her creative life." Upon reviewing for the associated album, Clash called it as the "stand out track" of the album, commented: "['Light On' is] where infectious energy and choppy beats are enough to bob Rogersâ characteristically peppy vocals over some of the prettiest melody you are likely to hear this year." Writing for Variety, Chris Willman said the track "gets passionate about feeling strangely passionless."
On November 3, 2018, Rogers performed the song during her appearance on the forty-fourth season of Saturday Night Live. The performance was met with a mixed response, with Bustle called it as "may not have been the best introduction". She performed it on Ellen on January 16, 2019.
