On 19 September 2018, an audio snippet from the song was released on the band's Twitter page. Guiding Light premiered on 20 September 2018 on BBC Radio 1. The song is described as a "dizzying folk-rock song that builds, builds, explodes and then explodes again".

Speaking to Annie Mac on Radio 1 about the single, Marcus Mumford said: "It was a bit of a beast to try and get on record. It was hard work. We kind of tried it in loads of different ways...this one took a while. We wrote it like a year ago, but it’s taken a while to just get it to that point and now we're happy with it." A lyric video was released simultaneously with the premiere of the track. The song made its television debut on the Tonight Show with Jimmy Fallon, and was later played on The Graham Norton Show, Saturday Night Live, and BBC Live Lounge, with acoustic performances at Radio.com and Sirius XM. The official video premiered on 17 October 2018; it uses footage from the band's mini-concert, originally filmed outside the Tate Modern in London on 21 September 2018.
