As the saying goes, “The eyes are the windows of the soul.†For cars, headlights are like people’s eyes. Bright eyes can bring a clear line of sight, making it safer for drivers to drive at night. Just imagine that if there is a problem with the lights at night, traffic accidents are unimaginable. Therefore, timely maintenance of the lights is crucial to the driver, which not only guarantees the comfort of driving, but also enhances the safety of driving. Below, Dege gave everyone a detailed introduction about the car headlights related knowledge and maintenance skills.
The various uses of headlights 1, traffic lights: that is, we commonly known as the "little light", mainly to allow the body corner can be seen. This light should always be on in dim places such as darkness, rain or underground parking lots.
2, low beam: use at night when driving in urban areas. On the one hand, the city's roads have street lighting, do not need high beam to explore the road in the distance, just look at the road conditions before the car can be; on the other hand, the traffic volume of urban roads is large, if you open the high beam Not only does it cause the other vehicle to be dazzled during the meeting, but it also has an impact on the gaze of pedestrians on both sides of the road. In heavy rain, heavy snow and other energy situations, not only visibility is very low, but also the braking distance of the vehicle will increase a lot, so at this time it is best to open the low beam lights, so that other vehicles can find themselves at the furthest distance.
3, high beam: In the wilderness or no road lighting on the road more suitable for use high beam, but remember that when the car should be replaced back light, so as not to cause the other driver dazzle.
4. Turning lights: The most basic purpose of turning lights is to give other vehicles and passers-by turning signals to remind others when turning. Sometimes the turn signal can also act as a light in a narrow place so that the driver can observe obstacles on both sides.
5. Danger Flash: This is what we often call “Double Flash†or “Double Lightâ€. It is used as a signal to remind other vehicles and pedestrians that the car has a special situation. One is when there is a fault on the road or when a traffic accident occurs. Second, when the motor vehicle is being towed, both the tractor and the tow vehicle should turn on the hazard warning flash. In addition, when the motor vehicle is driving on the road, it is not possible to turn on the hazard warning flash light at will.
6. Fog lights: Fog lights are light signals used in fog weather. Fog lights have stronger penetrating power in fog, so it is easier for vehicles or pedestrians to notice them earlier.
7, reversing lights: reversing when the rear of the car will have a white reversing light, on the one hand can illuminate the rear of the road, obstacles, reduce the blind spot when reversing, on the other hand is a reminder to the rear pedestrians. The reversing lights are associated with the reverse gear and do not need to be operated separately. However, if the reversing light malfunctions, it should be repaired in time to avoid danger when driving at night.
Why do lights fail?
Problems with the lights are generally related to the quality of the lights, and the other is related to illegal modifications. The headlight is most afraid of water, if the lamp is not well sealed, it is easy to have water vapor, and the reflective surface is also easy to change color, so the light that comes out after the failure is problematic. Therefore, if the owner finds a fog in the morning when he is driving, wipe it off and turn on the lights. If the fog disappears within 40 minutes, there is not much problem with the headlights. If one hour later, the fog of the headlights still remains. In that case, it shows that there is a problem with the sealing of the lights.
How to prevent the lamp from malfunctioning?
1. Do not use inferior light bulbs. The "soul" of a headlight is its light bulb, and its performance will affect the effect of night lighting and is directly related to traffic safety. The poor quality bulb has a short life and cannot guarantee a stable quality. In addition, the poor quality bulb has insufficient brightness, inconspicuous focus, and a short-range range. When overtaking, the driver may experience visual illusion and be prone to accidents. Therefore, do not consider poor light bulbs when self-adjusting the headlamps or when they need to be replaced.
2, daily maintenance to do a good job.
3, do it yourself to adjust the lights. The correct beam position will make the vision more clear and the driving will be safer. In fact, when there is a problem with the lights, it is not necessary to go to the 4S shop to make adjustments. It is also very easy to do it yourself. You can choose a dim environment, such as an underground parking lot or at night, park the front end against a wall, align the front and the wall as much as possible, about 5 or 6 meters apart; turn on the lights and cover them with a light-proof thick cloth. Hold a headlight and adjust each headlight individually. Use a marker or chalk to mark the headlights in the center of the wall. Also mark the wall of the vehicle's center (front center). ; Measure the distance between the lamp marks on the two sides and the center position separately. The two distances should be equal. If there is a phenomenon of outward or inward deviation, you should look at the vehicle instruction manual, use a screwdriver to fine-tune, so that the position of the two lights is symmetrical; finally adjust the height of the beam, the right side of the light should be completely direct, The left headlights are about 10cm higher, but do not turn them too high so that the lights will not reach the driver's eyes directly. The right-hand headlights can be shifted to the right to increase the visibility of the right side of the vehicle. The entire process is about 15-20 minutes and it is very easy.
Lamp Maintenance Tips 1. Use a soft cloth to wipe off the dirt, debris, and debris from the headlamp surface.
2. Clean the headlights every three months with soap and water. This prevents accumulation of dirt, etc., and avoids yellowing of the headlights.
3. Polish the headlights after cleaning, wipe the headlights with chemically synthesized polishing agent, and wax the headlights according to the procedure.
4. When not using the car, park the car in the garage or in the shade. It will help to reduce the headlamps being exposed to ultraviolet radiation and causing the polycarbonate to be oxidized.
