Abstract

The arrangement of automatic winking lights for road works uses several classic transistor bistable circuits which mutually trigger each other and which are associated with electric light sources. The transistor circuits triggering and extinguishing the light sources one after the other. The transistor circuits are in the form of identical modules having various outputs which permit various forms of use. The first module operates as the pilot, and whilst actuating the lighting and extinction of a luminous source, triggers with a certain time delay, a second repeater module which also actuates illumination and extinction of a light source, and triggers in its turn, with time delay, a third repeater module and so on.
