Système de clignotement de changement de direction et d'avertissement pour un véhicule automobile

The invention relates to a direction indicator and hazard flashing light system for motor vehicles, consisting of a load-controlled flasher unit, a hazard warning switch and a direction indicator switch. According to the invention, a separate load-controlled flasher current path with a separate current demand is provided for hazard warning and for direction indication, the paths being separatedly but synchronously switched by a flasher relay which is constructed as a double contact relay. The separate current demand permits activation of the direction indicator switch to be distinguished from activation of the hazard warning switch and also their simultaneous activation to be detected unambiguously. This possibility is utilised in a development in such a way that when the two flasher switches are activated simultaneously the flasher relay is not activated and thus opened while a flasher current is fed into the direction indicator path by an auxiliary clock transmitter. The flasher system according to the invention reduces the outlay on cabling and load switching relays in comparison with known flasher systems with a comparable range of functions.
