"WHEN THE LIGHTS GO OUT" is about how a guy is trying to win a girls heart. It was 5ive's first single and it spent the entire summer in the Billboards top ten in the U.S. In Europe it was 5ive's second single and it went up to number four on the U.K. pop charts. In the video the guys are in a bowling alley. Dancing on the lanes while Abs does a little deejaying. The guys alternate singing verses with Sean. They also alternate singing the chorus.
