Car lights routine maintenance and repair methods

Long working hours, people will appear tired eyes, the car is no exception. Let's take a look at the daily car lamp maintenance and repair.
Checking the Outside Lamp Bulb burn out is an extremely quick and easy job, but a complete and systematic maintenance of the outside lamp is not that easy. Timely maintenance of exterior lighting is of crucial importance to the driver as it affects not only the comfort of driving but also the safety of driving. Before getting a reminder, it's hard for car owners to realize that the headlights, taillights, turn signals or parking lights are no longer working properly. Incidentally, the job of replacing a burned out bulb is very simple, and the cost of DIY is lower than the charging standard for lighting system maintenance at the service station.
More often than not, the failure of the lamp is not limited to small problems such as lamp burnout, socket corrosion or plug damage, and often require professional diagnostic techniques to analyze the root cause of the fault. Even those low-cost cars, its internal and external lighting is controlled by the host computer. And those luxury cars, only the headlights on the three computers to control.
If the car is equipped with DRL (Gallery Forum), you must first understand the working principle of these devices. For example, some daytime running lights can not turn on the daytime running lights before the engine starts. Some daytime running lights can not work normally even if the parking brake has not been canceled even though the engine has been started. If the vehicle is equipped with light-control lights (that is, the system has the function of automatically turning on the headlights when the outside light dims to a certain extent), check the operation of the light from the weakest to the strongest state, of course Also do not neglect to check the auto-off timer. If the system is equipped with a timer, set it as the maximum delay.
If the headlight is damaged, a similar fixture is usually used to replace it. Some cars are equipped with a high-intensity discharge headlamp HID that generates high-density light from high-voltage arc discharges generated by their predesigned electronic systems. Note that normal quartz-halogen bulbs can not be used here. Also, check the headlamps for cracks, because although the surface cracks do not affect the headlamp's performance, moisture penetrates the cracks along the fixture, which will inevitably reduce the life of the lamp.
The calibration of the headlight direction of illumination should also be included in the list of maintenance items as the headlamp must be able to provide good forward lighting of the traveling vehicle in order to ensure maximum driving safety of the driver.
Seize the key, we must not forget to test other lights, such as turn signals, license plate lights, show width lights, parking lights, reversing lights and brake lights (including the middle high brake light CHMSL) and so on. In addition, many vehicles also fog lights as standard equipment or popular options, fog lights are generally installed in the car on the lower position, so vulnerable to rock damage, in its maintenance, in addition to check the lighting system In itself, the light of the cracks should not be ignored.
