"Green Light" is an R&B/funk song written by Beyoncé Knowles, Sean Garrett, and Pharrell Williams for Beyoncé's second solo studio album, B'Day (2006). Co-produced by The Neptunes and Beyoncé, it was released as the fifth UK single on July 30, 2007. The song received mixed responses from contemporary critics.
The single performed moderately on charts. "Green Light" peaked on the UK Singles Chart at number 12 and at number 46 in Ireland. The Freemasons remix of the track peaked at number 18 on the Dutch Top 40 chart. Its accompanying music video is inspired by Robert Palmer's 1985 music video "Addicted to Love". Beyoncé considered the video her toughest shoot, and features her all-female tour band Suga Mama for the second time.
