White Light (Namie Amuro song)

"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 originally planned 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" was released. 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 is a midtempo Christmas song with lyrics about love and holiday festivities.

Music critics praised Amuro's interpretation of Christmas music with "White Light", noting her vocals and the chorus sections as highlights of the song. Commercially, it performed moderately in Japan, peaking at number seven on the Oricon Singles Chart. The physical format was certified gold by the Recording Industry Association of Japan (RIAJ) for exceeding 100,000 units, while the digital version of "White Light" was certified gold for selling more than 100,000 copies in the region.

A music video was filmed by Masashi Muto and features Amuro in a "romantic world", as noted by the singer, and was visually inspired by the Christmas season. It also served as the commercial theme for the Japanese ringtone service Dwango Iromelo Mix. Since its release, "White Light" has appeared on Amuro's greatest hits album Best Fiction and her ballad-inspired compilation album Ballada (album) (2014). It was also included on three of Amuro's concert tours and subsequent live albums.
