Knowledge of using car headlights

The headlights are like the eyes of a car, playing a role both day and night. However, they are mainly made of glass electronic products, so they are relatively delicate. If used and maintained improperly, the lifespan of the headlights will be reduced, leading to a series of malfunctions. Therefore, understanding the relevant knowledge of the use of headlights can better use them and ensure driving safety.

Why do car lights malfunction

In addition to the normal lifespan of the car lights, problems with the car lights are generally related to the quality of the car lights, and also to illegal modifications. The biggest fear of headlights is water ingress. If the headlights are not properly sealed, it is easy to have water vapor, the filament, etc. are also prone to burning out, and the reflective surface is also prone to discoloration. Therefore, there is a problem with the light emitted after a malfunction.

Reminder:

If the car owner discovers fog in the headlights when driving in the morning, and after wiping it off, turns on the headlights. If the fog disappears within 40 minutes, there is not much problem with the headlights. However, if the fog is still present after an hour, it indicates that there is a problem with the sealing of the headlights. Whether the car lights will have problems is primarily related to quality, and also to installation. If there is a problem with the car lights during maintenance and the coordination between different programs is not good enough, there is a possibility of poor sealing.

How to avoid malfunctioning car lights

To prevent abnormal malfunctions in the headlights, it is necessary to pay attention to their normal use. Firstly, the headlights should not be soaked in water. When a car is driving, the splashing water from the front will generally have no impact on the headlights. However, if the front hood is opened and the engine and headlights are washed with a water gun during car washing, the headlights are very prone to water ingress. Some manufacturers stipulate that when washing the car, the engine can only be wiped with a cloth, not washed with water. Because the plastic used for fixing the installation position of the car lights only has a dustproof function, not a waterproof function.

Reminder:

It is best to use original parts for the car lights, as illegally modified car lights may experience melting, bursting, and incorrect reflection. During the installation of the car lights, it is stipulated that hands should not be used to touch the light bulb, as if sweat stains remain on the car lights, they may burst. In addition, when modifying the car's headlights, it is necessary to comply with the original requirements of the car, such as the specified wattage of the headlights, whether xenon lamps or halogen lamps are used, etc. It is relatively easy to distinguish the situation of fog entering the headlights, and other situations should be quickly repaired. Nowadays, there are more electronic components used in car headlights and more high-voltage electricity is used, so it is also important to be careful of the voltage of the car headlights when modifying.

How do car owners self check for car lamp malfunctions

If the effect is not satisfactory, it is advisable to go to a 4S store for repair or debugging. High beam headlights do not focus, low beam headlights focus, but high beam headlights do not necessarily mean that more is better. When a 4S store repairs a car, the main focus is to observe the brightness and height of the headlights, as well as whether there is water ingress or bursting. It is also easy to identify any defects when repairing the headlights. Moreover, if the car owner wants to distinguish whether the headlights are faulty, the main thing is to see if the headlights are secure, whether there is spotlight, whether there is water ingress, and so on.

Usually, conditions such as dark headlights, lack of focus, water ingress, and dust ingress are not considered important by many car owners and are completely indifferent. Usually, after 4-5 years, car owners do not care much unless they pass the annual review. Against this backdrop, only a portion of car owners have chosen to return to 4S stores for car repairs. However, this situation is not applicable. Due to the problem with the headlights, regardless of their size, it can pose a certain threat to driving safety. Therefore, regardless of annual inspection or not, as long as the headlights are in good condition, they should be returned to the factory for inspection and repair in a timely manner.

Reminder:

The quality of the manufacturer's original parts will not be affected, while the quality of the secondary parts may encounter various problems. For 4S stores, there are not many methods to distinguish between original and auxiliary parts. Generally speaking, the original parts have confidence in quality, so they are not labeled with a sales date during sales, while auxiliary parts have a sales date to determine the warranty period. Another way to distinguish is to see the clarity of the relevant markings.
