"White Light" is a song by Japanese singer Namie Amuro. It was released by Avex Trax in Japan on November 16, 2005, as a double A-single with "Violet Sauce". "White Light" was supposed to promote Amuro's eighth studio album Play (2007), but it was scrapped from the final track list. Instead, an alternative version of "Violet Sauce" appeared. A demo version of the song was sent to Amuro, who decided it needed a warmer tone and reworked it as a Christmas song. It was modified by Nao'ymt, the song's sole composer, producer, and writer. Musically, it's a midtempo Christmas song with lyrics about love and holiday festivities.
