Trafficator is a semaphore signal which, when operated, stands out of the motor vehicle bodywork to indicate its intention to turn in the direction indicated by the pointer signal. Trafficators are often at the door of the pillar.

History
They first appeared in the 1900s, when they were mechanically or pneumatically driven. In 1908, Alfredo Barrachini in Rome added electric lights inside the arm that was lit as they elongated, but his operation was still using a cable system. The electric surgery came in 1918 when Naillik Motor Signal Company of Boston added an electric motor drive. The system was replaced by two French inventors, Gustave Deneef and Maurice Boisson, who used linear solenoid in 1923. The last complete system came in 1927 when Max Ruhl and Berlin-based Ernst Neuman combined internal lighting and solenoid operations.
They are common on vehicles until the introduction of flashing amber, red or white indicator at or near the corners of the vehicle (and often along side as well). They are increasingly scarce since the 1950s, because the ever-tougher law has determined the need for this kind of modern flashing signal. Many historic vehicles (such as the pre-1960 Volkswagen Beetle cars sold outside the US) used on roads today have been equipped with traffic regulators or replaced with modern indicators to help visibility and meet legislative requirements. Trafficators can now be installed with flash lights as upgrades.
