How to Troubleshoot the Head Lamp?

As a Zotye Head Lamp Supplier China, share with you.

It is an extremely quick and simple task to check the bulbs of exterior lamps and lanterns burned out. However, it is not so simple to carry out comprehensive and systematic maintenance of exterior lamps. Timely maintenance of exterior lights is very important for drivers, because it not only affects the driving comfort, but also directly affects driving safety. It is often difficult for car owners to realize that the headlights, taillights, turn signals or parking lights are not working properly before being reminded. By the way, the work of replacing a burnt out bulb is very simple, and the cost of DIY is lower than the charging standard for maintenance of the lighting system at the repair station.

In more cases, the failure of car lights is by no means limited to small problems such as burned bulbs, rusted sockets, or damaged plugs. Professional diagnostic techniques are often needed to analyze the root cause of the failure. Even for low-priced cars, the internal and external lamps are controlled by the main computer. For those luxury cars, only the headlights are controlled by three computers.

If the car is equipped with DRL, you must first understand the working principle of these devices. For example, some daytime running lights cannot be turned on before the engine is started, and for some daytime running lights, if the parking brake has not been cancelled, even if the engine has been started, the daytime running lights still cannot work normally.

If the vehicle is equipped with light-controlled lights, you may wish to check the working conditions of the lights during the process from the weakest to the strongest sensitivity. Of course, do not neglect to check the automatic shutdown timer. If the system is equipped with a timer, set it to the maximum delay.

If the headlights are damaged, they are usually replaced with similar lamps. Some cars are equipped with high-intensity discharge headlights HID, which generates high-density light sources through high-voltage arc discharge generated by its pre-designed electronic system. Note that ordinary quartz-halogen bulbs cannot be used here.

In addition, check the headlights for cracks, because although surface cracks will not affect the lighting performance of the headlights, moisture will penetrate into the lamps along the cracks, which will inevitably reduce the service life of the bulbs. The calibration of the headlight direction should also be included in the list of maintenance items, because in order to ensure the maximum safety of the driver, the headlight must be able to provide good forward lighting for the moving vehicle.
