"Baby When the Light" is a song from 2007 by the French DJ David Guetta. It first appeared on Guetta's Pop Life album and features vocals by singer Cozi Costi. The song 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 song was released in late 2007. The CD pressing of this single features four versions of "Baby When the Light" including the Album Version, Original Extended Version and David Guetta and Fred Rister Remix Radio Edit.

The "Baby When the Light" music video is about a young girl (played by model Kelly Thiebaud, who also appears in "Love Is Gone" video) who goes to the beach and dreams about befriending a handsome surfer. While walking her dog, she decides to rest on the beach where she starts dreaming. As the video proceeds, strange things start to happen (girls in bikinis start dancing, an old woman starts rubbing herself with lotion as she watches the young surfer via binoculars). Close to the end of the video, the woman is finally approached by the surfer after exchanging smiles throughout the video. He then invites her to surf with him. The video ends as the girl wakes up from her dream, and finds no one around her but her dog.

The Lightning Seeds are an English alternative rock and pop band from Liverpool, England formed in 1989 by Ian Broudie (vocals, guitar, producer), formerly of the Big in Japan band.

Originally a studio-based solo project for Broudie, The Lightning Seeds expanded into a touring band following Jollification (1994). The group experienced commercial success throughout the 1990s and are well known for their single "Three Lions", a collaboration with David Baddiel and Frank Skinner which reached No. 1 in the UK in 1996 and 1998.

In 1989, Ian Broudie began recording alone under the name "Lightning Seeds". Broudie had previously been a member of the band Care in the mid-80s, but by '89 was much better known as a producer for Liverpool-based chart acts Echo & The Bunnymen and The Icicle Works.

Working as a singer/songwriter/multi-instumentalist/producer, Broudie (in his guise as "The Lightning Seeds") achieved success with the psychedelic and synthpop hit "Pure", from the album Cloudcuckooland, which reached the UK Top 20. The same year "Joy" and "All I Want" were also released but failed to make an impression. "Pure" had some success in the United States Billboard Top 40 reaching #32. Both "Pure" and "All I Want" also reached the Modern Rock Tracks top 10.
