Lightning is a game mode in Bejeweled 3, Bejeweled Classic, and the HTML version of Bejeweled (known as Speed). The name of this game mode is most likely a reference to Bejeweled Blitz, as "blitz" means "lightning" in German. The in-game music featured in Lightning mode is even a modified extended version of the music featured in Bejeweled Blitz. It originally did not appear in Bejeweled Classic, but it became available via an update that was released on July 12, 2012 in the iOS versions and February 22, 2016 as a paid game mode in the Android version.
