In bad weather such as rain, fog, sand and dust, in addition to slowing down and driving carefully, you also need to pay special attention to the lights of the car, that is, how to use fog lights?
1. The position of the vehicle body fog lights
According to my country's "Installation Regulations for Exterior Lighting and Light Signaling Devices of Cars and Trailers (GB4785-2007)", cars must be equipped with 1-2 rear fog lights. If only one rear fog light is equipped, it should be installed on the left side of the vehicle's forward direction. Side, the height from the ground is not less than 250mm, but not more than 1000mm; the front fog lights are optional, the color of the front fog lights of the car should be white or yellow, the height from the ground is not less than 250mm, and the color of the rear fog lights must be red.
2. Turn on the fog light position in the car
The front fog lamp is generally located at the lower part of the front bumper of the car, and some are located at the innermost side of the headlight group. As for the rear fog lights, choose the same warning red color as the brake lights. Why are there usually one rear fog light? Because if two rear fog lights are to be installed, the distance between the fog lights and the brake lights should not be less than 10 cm. In order not to destroy the beauty of the rear of the car, only one is used. Because the cab in mainland China is located on the left side of the car, that is, the left-hand drive, the rear fog lights are more located on the left side of the rear of the car, which attracts the attention of the driver behind.
3. Correct use of fog lights
First, let’s take a look at the official description of fog lights:
1. When the visibility is 200-500 meters, the low beam headlights, width lights and tail lights must be turned on, the speed must not exceed 80kmh, and a driving distance of more than 150 meters must be maintained with the vehicle in front of the vehicle driving in the same lane;
2. When visibility is 100-200 meters, fog lights, low beam lights, width lights and tail lights must be turned on, the speed must not exceed 60kmh, and a distance of more than 100 meters from the vehicle in front must be maintained;
3. When the visibility is 50-100 meters, the fog lights, low beam lights, width lights and tail lights must be turned on, the speed must not exceed 40kmh, and the distance from the vehicle in front should be more than 50 meters.
4. When visibility is less than 50 meters, the public security traffic control department will take traffic control measures to close part or all of the highway in accordance with regulations.
According to my country's traffic regulations, fog lights will only be activated when the visibility is 200 meters and below, which means they are basically used in rain, snow, fog, and sand and dust weather. In actual situations, we found that most vehicles did not turn on the fog lights as required, but more often turned on the double flash. In this case, it is completely wrong to turn on the double flash.
4. The dangers of misuse of fog lights
Fog lights were invented to make up for the shortcomings of low beam lights that cannot penetrate dense fog and heavy rain. They are only emergency lighting tools in bad weather, so they cannot be used as daily lighting tools. Fog lights have no hood and have high luminous power, and the light source has strong penetration. If a car turns on its fog lights at night, it can easily affect the driver's attention in the opposite lane or the car behind it, and it can easily cause visual fatigue and lead to accidents. Facts have proven that the misuse of fog lights is as harmful as high beam lights. For the safety of ourselves and others, we must not turn on the front and rear fog lights when we are in a clear day or night.
Finally, I would like to remind car owners: When encountering bad weather such as rain, snow, sandstorms, etc., be sure to turn on the fog lights normally and never use double flash lights, because double flash lights are used when the car breaks down. If you turn on all double flash lights, If the lights are flashing, the car behind will think that all the cars are out of order and cannot drive normally, which will cause traffic jams or cause other traffic accidents. In addition, it will affect the ability of car owners who actually encounter double flashing lights and car breakdown to get rescue in time.
