"Red Light" is a song by rock band U2.
Taking advantage of American musical group Kid Creole and the Coconuts being in Dublin, U2 invited the trumpet player to work on "Red Light", thinking that it would freshen up the sound of the band.
Bono said, "We had the studio lit red for effect, and one Coconut took her top off and sang in what looked like a ballerina's bra.
"[1] Sid Smith of the BBC wrote of the song, "U2's palette broadens on 'Red Light' with backing vocals from Kid Creole's Coconuts no less, and some equally superfluous trumpet – the latter making a tokenistic jazz noise atop the impervious surface of the band's default setting, that only loosens up enough to work effectively by the time the track is fading-out.
"[2] Sputnikmusic contributor, John Cruz, felt the song indicated a change of tone on the album, saying: "The album's mood becomes looser, with Bono chasing hopeless love in Red Light".
