In recent years, the domestic automobile market has also developed rapidly. Every household basically has its own scooter. As a large consumer product, it ranges from tens of thousands to millions. As car owners, I don’t know if you are on the road. When driving on, the other side's vehicle turned on a few lights. Most of the driver's friends thought that the other side was provoking themselves, so they responded a few times. In fact, the lighting problem is not what the driver's friends think! There are other meanings. "Car light whispers" often used by old drivers, when others flash your headlights at you three times, you have to pay attention to the headlights flashing once. Waiting for a car at an intersection, when the green light is on, sometimes you will encounter the situation that the car in front is a novice, and there is a nervous wave of hands, a slow start, etc.; maybe the driver in front is distracted and neglects the signal light prompt. At this time, it is obviously not appropriate to honk the horn. We can replace the rough horn noise by flashing the headlights to remind the vehicle in front to move forward or give up the lane.

Merge onto the vehicle. When driving on an expressway or at an elevated ramp, there are often vehicles merging, especially when vehicles are going to pass alternately. If the communication between drivers is not smooth, traffic accidents are prone to occur. At this time, if there is a vehicle prompting When changing lanes, a clear response must be made to whether to agree or refuse. Therefore, the headlights play a role in communication. Generally, one flash means "agree" and continuous flash means "rejection".
