The car lights can also be adjusted by yourself. In order to drive safely, it is necessary to adjust the lights regularly, especially for the car owners who often drive at night.
First, choose a night to park your car against a wall. Let the front of the car and the wall as vertical as possible, and keep a distance of about 10 meters. Then find a friend to sit in the car and adjust the lights with you. First, turn on the lamp, cover one lamp with a thick cloth, and record the projection of the lamp on the wall with chalk. Both the left and right lamps should be equidistant from the central axis of the car. If the phenomenon of outward or inward deviation occurs, it must be adjusted with a screwdriver according to the instructions in the vehicle manual.
As for the height of the light beam, the right light should be completely horizontal and straight, while the left light should be raised by 10 cm. The width should also be adjusted. Use another screwdriver in the manual to adjust. The left headlamp should be absolutely straight forward, and the right headlamp can be slightly tilted to the right, because the lower part of the right side can also be seen clearly, especially in foggy weather.
Car lamp maintenance and repair
If the car is equipped with DRLs, then we need to understand the working principle of these devices. Some day lights cannot be turned on before the engine starts; There are also some daily running lights. If the parking brake has not been cancelled, even if the engine has been started, the daily running lights still can not work normally. If the vehicle is equipped with light control lamp, then you need to check the working condition of the lamp in the process of light sensitivity from weak to strong. Of course, don't neglect to check the automatic off timer.
If the headlamp is damaged, it is usually replaced with a similar lamp. Some cars are equipped with high intensity discharge headlight hid, which generates high density light source by high voltage arc discharge generated by its pre designed electronic system. Then ordinary quartz halogen bulb can not be used here. Pay attention to the calibration of the light direction of the headlamp to ensure the safety of the driver.
Check whether there are cracks on the surface of the headlamp, because although the surface cracks will not affect the lighting performance of the headlamp, the moisture will penetrate into the lamp along the cracks, which will certainly reduce the service life of the bulb. If the situation is serious, it will also cause the short circuit of the circuit.
In addition to the headlights, we should not forget that other lights, such as brake lights, turn signals, fog lights, etc., can not be ignored and should be checked, because the functions of these lights can not be replaced by other light systems. Only when they do their own duties, can driving safety be guaranteed.
