VEHICLE CHANGE-OF-DIRECTION INDICATOR Russian patent published in 1995 - IPC

FIELD: indicating facilities. SUBSTANCE: indicator has multivibration-type generator 1 and stable current generator 1. Connected in parallel with input circuit of output transistor 3 is protection circuit. Collector of transistor 4 is connected between base and emitter of transistor 4. Emitter of transistor 4 is connected additionally to "plus" terminal of vehicle circuit. Electric circuit is supplied through low-ohmic resistor 5. Groups of vehicle-carried lamps 7,8 are connected with collector of output transistor 3 through switch 6. Offered indicator is serviceable without additional adjustment and can be used on vehicles with different circuit voltages, even after cleaning short circuit faults in vehicle-carried lamps circuit. EFFECT: enlarged operating capabilities. 1 dwg
