"Baby When the Light" is a song by French DJ David Guetta.

It was released on 10 November 2007 as the third single from his third studio album, Pop Life.

It was written by Guetta and singer-songwriter Cathy Dennis, whose previous hits include "Touch Me (All Night Long)" as well as co-writing numerous dance-pop songs such as Kylie Minogue’s "Can't Get You Out of My Head" and Britney Spears' "Toxic".

The "Baby When the Light" music video is about a young girl, played by model Kelly Thiebaud, who goes to the beach and dreams about befriending a handsome surfer.

The video ends as the girl wakes up from her dream, and finds no one around her but her dog.
