【Car owner's car knowledge】Headlights are like the eyes of a car. They play a role whether it is day or night, but because they are mainly glass electronic products, they are also relatively delicate. Therefore, if you understand the relevant knowledge of the use of car lights, you can better use the lights to ensure driving safety. Let Cai Zhiwei, a senior after-sales technician from a FAW Toyota dealer, tell us some relevant knowledge.
Why does the PART1 headlight fail?
Master Cai told reporters that in addition to the normal life of the lights, the problems with the lights are generally related to the quality of the lights, and the other is related to illegal modifications. The most feared thing about headlights is water ingress. If the headlights are not well sealed, water vapor will easily occur, and the filaments will be easily burned out, and the reflective surface will also be easily discolored. Therefore, there will be problems with the light emitted after the failure.
remind:
If the car owner finds the headlight foggy when driving in the morning, turn on the headlight after wiping it off. If the fog disappears within 40 minutes, the headlight will not be a big problem, and if the fog is still there after an hour, That means there is a problem with the sealing of the headlights. Whether there will be a problem with the lights, first of all, it is related to the quality, and the other is related to the installation. If there is a problem with the lamp during the maintenance process, and the coordination between the different procedures is not good enough, there may be a situation of poor sealing.
PART2 How to avoid car lights from malfunctioning
Master Cai said that in order to prevent abnormal failures of the lights, we must pay attention to the usual usage. First of all, the headlights cannot be soaked in water. When the car is driving, the water splashing from the front will generally not have any effect on the headlights. If the front cover is opened when the car is washed, the engine and lights are flushed with a water pressure gun. , then the headlights are very easy to enter the water at this time, and some manufacturers such as FAW Toyota stipulate that when washing the car, only the engine can be scrubbed with a cloth, and cannot be washed with water. Because the plastic used in the fixed installation position of the car light only has the function of dustproof, but not waterproof.
remind:
It is best to use the original parts for the headlights. The illegally modified headlights may melt, burst, and reflect asymmetrically. During the installation of the lights, Toyota stipulates that you cannot touch the bulbs with your hands, because if there is sweat on the lights, the lights may burst. In addition, when the headlight is modified, it must meet the original requirements of the car, such as the wattage specified by the headlight, whether the xenon lamp or halogen lamp is used, etc. It is relatively easy to distinguish the situation that the headlight enters the fog, and other situations occur. To be repaired immediately. Now the lights use more electronic components and use more high-voltage electricity, so be careful about the voltage of the lights when refitting.
PART3 How car owners can self-check the lamp failure
If the car owner feels that the headlight is not very suitable or ideal when using it, it is best to go to the 4S shop for maintenance or debugging. The high beam does not have the function of focusing, and the low beam has the function of focusing, but the high beam is not to say that the higher the better. When 4S shops are doing car maintenance, they will mainly check whether the brightness and height of the lights are normal, whether there is water ingress, whether there is bursting, etc. It is easy to identify whether there is a problem with the lights during the maintenance process. If the owner wants to identify whether there is a problem with the lights, he mainly depends on the intensity of the lights, whether there is spotlight, whether there is water ingress, etc.
Master Cai told reporters that, generally speaking, many car owners don't care about the dark lights, no light, water, dust, etc., and they don't care about it at all. It doesn't matter much, unless it is said that the annual review cannot be passed. In this case, some car owners will choose to go back to the 4S shop to repair the car. However, this situation is not suitable, because there is a problem with the lights, no matter the size, it will pose a certain threat to the driving safety. Therefore, regardless of whether the annual inspection is carried out or not, as long as the lights are in condition, it is necessary to return to the factory for inspection and maintenance in time.
remind:
There will be no problems with the quality of the original parts of the manufacturer, but there may be various problems with the auxiliary parts. For 4S stores, there are not many ways to distinguish between original parts and sub-factory parts. Generally speaking, the original parts have confidence in the quality, so the sales date will not be posted when they are sold, while the sub-factory parts will be sold. date to determine the duration of the warranty. Another way to distinguish is to look at the clarity of the relevant logo.
