After only pressing the emergency switch 1, the left and right turn signals 3 and 5 will light up at the same time. At this time, no matter where the turn switch 7 is turned, the turn signals 3 and 5 will flash at the same time, and the turn or lane change indication will be invalid. , at this time, the drivers of pedestrians and other vehicles cannot correctly judge the driving intention of the vehicle that turns on the emergency lights, which will bring danger to pedestrians or drivers.

The invention discloses a control circuit for an automobile steering signal lamp and emergency lamp. The control circuit comprises a steering signal lamp switch, an emergency lamp switch, a left flasher, a left steering signal, a right flasher and a right steering lamp; the left flasher and the left steering signal are connected in series, the right flasher and the right steering lamp are connected in series, the emergency lamp switch is a double-pole single-throw switch, and the emergency lamp switch is a double-pole double-throw switch; a normally-switched-off relay is serially connected to a left and right emergency signal circuit. When the emergency lamp is switched on, the steering lamps are capable of indicating the steering or lane change intent according to the operation of a driver constantly, securities of automobiles and pedestrians are guaranteed, and safety is improved.
Description
technical field [0001] The invention relates to the field of control of automobile signal lamps, in particular to a control circuit for automobile turn signal lamps and emergency lamps. Background technique [0002] At present, automobiles are equipped with turn signal lamps for indicating turning or lane change intentions on the head, tail, or even body fenders or rearview mirrors. This turn signal lamp is of great significance to ensure the safe driving of drivers. The turn signal light is an active safety part of the car, not only indicating the intention of turning or changing lanes, but also used to indicate emergency or formation travel when double flashing. Since the turn signal lights and the emergency lights use a set of lights at the same time, in some specific occasions, such as weddings, funerals, and weddings, the emergency lights are used as the team logo, and the emergency lights need to be turned on in rainy and foggy days to remind the other side of pedestri...
