The first incarnation of Pepsi Light was cola and lemon flavor with 50% fewer calories. It was soon replaced with lemon-flavored diet cola of the same name in the 1970s and 1980s in the United States called Pepsi Light, which was lemon-flavored by necessity to counteract the aftertaste of the artificial sweetener saccharin. When aspartame became more widely available, the lemon flavoring was removed from the newly rechristened Diet Pepsi.
