The maintenance of the lights is a trick!
Checking out the burn-out fault of the exterior lamp is an extremely quick and simple task, but it is not so simple to carry out a comprehensive system of maintenance of the exterior lamps. Timely maintenance of exterior luminaires is essential for drivers, as this not only affects the comfort of the car, but also directly affects the safety of the car. It is often difficult for owners to realize that headlights, taillights, steering lights or parking lights are no longer working until they are alerted.
In more cases, the failure of the lamp is not limited to the light bulb burn, socket rust or plug damage such a small problem, often need to use professional diagnostic techniques to analyze the root cause of the failure. Even for low-cost cars, the internal and external luminaires are controlled by the main computer. Those luxury cars, with their headlights alone, are controlled by three computers.
If the car is equipped with a daily light system DRL you must first understand how these devices work. For example, some daylights cannot be switched on until the engine is started, and some of the daylights are not working properly if the parking brake has not been cancelled, even if the engine has started. If the vehicle is equipped with a light control light (when the outside light is dim to a certain extent, the system has the function of automatically turning on the headlights), you may wish to check the light from the weakest to the strongest state of the operation of the lights, of course, do not ignore the check automatic off timer. If the system is equipped with a timer, set it to the maximum delay.
If the headlights are damaged, a similar lamp is usually replaced. Some cars are equipped with high-intensity discharge headlights HID, which generates high-density light sources through high-voltage arc discharge spawned by its pre-designed electronic system. Note that ordinary quartz-halogen bulbs cannot be used here. In addition, also check the headlights for cracks, although the surface cracks will not affect the lighting performance of the headlights, but moisture along the cracks will seep into the lamp, which will inevitably reduce the life of the bulb.
The alignment of the orientation of the headlights should also be included in the maintenance item list, as the headlights must be able to provide good lighting for the vehicle in motion in order to ensure maximum safety of the driver.
Grasp the key, but also must not forget to test other lighting systems, such as steering lights, license plate lights, wide lights, parking lights, reversing lights and brake lights (including the middle high brake light CHMSL) and so on. In addition, many vehicles also use fog lights as standard equipment or popular optional, fog lights are generally installed in the lower position of the car, so it is highly susceptible to stone damage, in the maintenance of it, in addition to checking the lighting system itself, the cracks should not be ignored.
