"Bajo Otra Luz" ("Under Another Light") is the third single released by Nelly Furtado during a special iTunes promotion counting down to the release of her fourth studio album, Mi Plan. The song features Julieta Venegas and La Mala Rodríguez vocals and was written entirely by Venegas. The song was later released for radio airplay on May 4, 2010.

"Bajo Otra Luz" was released as promotional download single on August 31, 2009 as part of the countdown to the release of Mi Plan. It was the third track to be lifted for a promotional release. The version released to iTunes does not include Julieta Venegas' vocals, as she was unable to record vocals for the single edit due to pregnancy. Instead, Spanish singer Celia Palli recorded vocals for the single edit.

According to Furtado's Twitter account, the music video for "Bajo Otra Luz" was recorded between May 15 and 16, 2010. Julieta Venegas does not appear in the video because of her pregnancy. The video was released July 1, 2010 and features Furtado and La Mala Rodríguez through the streets of Little Italy, Toronto wearing different costumes and suits. Furtado expresses the theme of the video to being humorous and fun. Wearing popular costumes such as a cavewoman, she-devil, Bjork's swan dress, Native American, Britney Spears and even paying homage to the Wizard of Oz's Dorothy character. On Furtado's Vevo page, as of October 2015, "Bajo Otra Luz" has received over 9,300,000 views.

The lyrics talk about a new relationship, which the protagonist is very proud of because she feels that her life has completely changed. Verses like "El color de mi vida cambió desde que tú llegaste" ("The colour of my life changed since you came") showcase the song's meaning. The song was completely written by Julieta Venegas, and includes a rap verse in the bridge which was written and performed by La Mala Rodríguez. Amongst all of Furtado's releases, this is one of the few in which she does not have credit for writing.
