The Morgestraich (in Basel dialect, "Morgenstreich" in High German) on Monday morning marks the beginning of the Carnival in Basel. At exactly 4 am all the lights in the old town of Basel are turned off, and the Industrielle Werke Basel (the Industrial Works of Basel are the public utility organisation of the city) shuts down the streetlights. The only light remaining comes from the lanterns of the Cliques. There are two major types of lanterns, the large "Zugslaterne" (parade lanterns) that are wheel-mounted or carried by 2 to 4 people in front of the Cliques; and the head-mounted "Kopflaterne" (head lanterns) that every participant wears. Some Cliques have uniform "Kopflaternen" but traditionally during the Morgestraich, Clique members do not wear uniform costumes. This varied dressing is called "Charivari".
