The indication of the car lamp housing（2)

Situation 3: (car lamp housing)when encountering a vehicle, it is necessary to combine the lights: the headlights flash "agree", and the headlights flash "refuse"
In elevated or expressway and some ordinary roads, Lane merging is often encountered. At elevated ramps, traffic flow should pass alternately. In this case, if the communication between vehicles is not ideal, it is likely to cause vehicle collision accidents.
It is very dangerous to rush to each other's Lane in the road section where the lanes are merged or the traffic flow intersects. Cars that need to merge must not change lanes directly. When a car prompts that they need to change lanes, they must give clear instructions to the other party whether to agree to the other party's lane change or refuse the other party's requirements.
In case of merging or alternating traffic sections, the lane changing vehicle will first turn on the turn signal in advance, wait at the intersection of traffic flow, and tell the rear vehicle "can I change lanes?" If the rear car agrees, slow down and flash the headlights to indicate "agree to change lanes"; If it's inconvenient, flash the headlights a few times to say "no, I don't agree".

Situation 4: (car lamp housing)there is a problem with the adjacent car. Light language: the headlights flash three times
The doors of some cars are not closed properly, and the tire pressure of one tire of some cars is obviously insufficient... When you happen to see some problems of other cars while driving on the road, everyone will not turn a blind eye, but how can you tell the owner of the problem car at the first time?
In fact, in the light language, there are also light reminders that other vehicles have problems and need to stop and pull over for inspection. If you have any problems with your neighbor's car, you can flash the headlights three times in a row, and then flash the headlights three times when the driver in front notices the light. Of course, if someone flashes the headlights to you three times, you should also pay attention. Maybe there is something wrong with your car, and the rear car is giving you a kind reminder.

Situation 5: (car lamp housing)the rear car is too close to the car. Light language: turn on the brake light periodically
When driving on the highway, keeping an appropriate safe distance is an effective way to avoid accidents. However, sometimes some people like to drive at high speed with the car, and keep the distance close. In this case, the driver in front of the car will disperse some of his energy to "pay attention" to the rear car, and he can't help worrying about whether the rear car will hit himself because of untimely braking. At this time, the car in front should try to give a warning to the car behind, tell the car behind not to follow closely, and then use the brake light.

In the process of driving on the highway, the brake light has another use, that is, when the rear car is too close to his car, the driver of the front car can gently step on the brake to prompt the rear car "you are too close to me, you should stay away."
