Three on a match (also known as third on a match or unlucky third light) is a purported superstition among soldiers during the Crimean War to World War II. The superstition goes that if three soldiers lit their cigarettes from the same match, one of the three would be killed or that the man who was third on the match would be shot. Since then, it has been considered bad luck for three people to share a light from the same match. This superstition has become part of popular Western culture in films, novels and other art forms.
