Lights play a vital role when we drive at night. Everyone knows what driving lights and high beams mean, how to use them, and when to use them, but do you know what a marker light is? What is the difference between low beam and low beam? How to use it.

Marker lights, light literally, "show" means warning; "outline" has the meaning of outline, so the marker lights are a kind of warning lights, used to remind other vehicles to pay attention to the lights. It is installed at the edge of the top of the car, which can express both the height and width of the car.

General regulations stipulate that vehicles with a height of more than three meters must be equipped with marker lights, and vehicles with a width greater than 2.10m must be equipped.

For low-beam light, in order to illuminate at a short distance, the design requirements are large illumination range (160°), short illumination distance, and the illumination distance is about 30-40 meters.

Under what circumstances need to turn on the position lights?

1. When driving in a foggy day, the visibility is reduced and the line of sight is blurred. When the fog lights are turned on, it is necessary to turn on the enlightening profile lights, so as to provide a good warning effect to other traffic participants on the road.

2. In rainy weather, it still serves as a reminder. It serves as a warning to the car ahead and behind, and try to avoid causing injury.

3. When driving at night, the marker lights must be turned on. Traffic laws stipulate that when driving at night, the thick rear taillights and the marker lights must be turned on to remind the following vehicles.

4. When driving in the evening, this driving is the most difficult, because there are no street lights and the lights are not very bright, but for safety, it is still necessary to turn on the marker lights so that other vehicles can see.

The illumination distance of the low beam is about 30-40 meters. According to the experiment, when driving at a speed of 55 km/h at night, when the situation is discovered, the brake is immediately applied, and the stopping distance is exactly 30 meters. That is to say, the safe distance to brake immediately when driving at night when seeing an obstacle within the range of the low beam light is At 30 meters, the speed cannot exceed 55km/h.

When driving at night and turning on the low beam, the speed is generally controlled at 40km/h.

1. On roads without a central isolation facility or without a centerline, low beam lights should be used for night meetings at a distance of 150 meters away from the oncoming traffic in the opposite direction, and near-beam lights should be used when meeting vehicles on narrow roads, narrow bridges and non-motorized vehicles. Light

2. When a motor vehicle is driving at night without street lights, poor lighting, or in low visibility conditions such as fog, rain, snow, sand, hail, etc., low beams should be used when the vehicle behind and the vehicle in front driving in the same direction are driving at close range. light;

3. When a motor vehicle passes sharp bends, slopes, arch bridges, crosswalks or intersections without traffic signal control at night, it shall alternately use far and near lights to indicate.

4. When vehicles pass through road sections with good lighting conditions at night, dipped beams should be used.
