Traffic indicator

A traffic indicator for an automobile which may automatically cancel the flush signal on the indicator lamps without using a switch lever under electronic control. The traffic indicator comprises a sensor circuit for sensing the direction of the rotation of the steering wheel to provide cancel signals to a right latch circuit when the steering wheel gets from the right back to a point from a point at a certain distance from the neutral position, and to a left latch circuit when the steering wheel gets from the left back to a point from a certain distance from the neutral position. The interval of the flush signals from a flushing circuit may be changed by signals given from the outside such that a disconnection sensing circuit may be provided to change the interval of the flush signals in case of an emergency.
