Checking led car lights projector led lights to the light bulb to burn out failure is a very quick and easy job, but it is not so simple to perform system maintenance on the exterior lamps. Timely maintenance of the exterior projector led lights is vital to the driver because it not only affects the comfort of driving but is also directly related to the reliability of driving. Often it is difficult to realize that headlights, taillights, turn signals, or parking lights are not working properly until you are alerted to them. The following is a detailed description of how to maintain projector led lights.

Take professional diagnostic techniques
More often than not, projector led light failures are not limited to minor problems such as burned-out bulbs, rusted sockets, or damaged plugs, but often require specialized diagnostic techniques to analyze the root cause of the failure. Even for those low-cost cars, the interior and exterior lamps are controlled by the main computer. In the case of luxury cars, the headlights alone are controlled by three computers.
Understanding how it works
If the car is equipped with projector led lights, you must first understand how these devices work. For example, some projector led lights cannot be turned on until the engine is started. There are also projector led lights that do not work properly if the parking brake has not been removed, even if the engine has been started. If the vehicle is equipped with light-controlled lights (that is, when the external light is dim to a certain extent, the system has the function of automatically turning on the headlights), you may wish to check the work of the lights in the process of light sensitivity from weak to a strong state, and of course, do not neglect to check the automatic shut-off timer. If the system is equipped with a timer, please set it to the maximum delay time.
Replace the lamps
If the front projector led light is damaged, it is usually replaced with a similar lamp. Some cars are equipped with high power projector led lights, which generate a high-density light source through a high-voltage arc discharge generated by their pre-engineered electronic system. Note that ordinary quartz-halogen bulbs cannot be used in this application. Also, check the front projector led light for cracks, because although surface cracks do not affect the lighting performance of the headlight, moisture can seep into the lamp along the cracks, which will inevitably reduce the life of the projector led light.
Calibrating the direction
The calibration of the direction of the front projector led light should also be included in the list of maintenance items because, to ensure the reliability of the driver's driving, the headlights must be able to provide good forward lighting for the moving vehicle.
Check other light systems
While capturing the key, it is also important not to forget to check other light systems, such as turn signals, license plate illumination lights, wide lights, parking lights, reverse lights, and brake lights (including the center high-mounted brake light CHMSL). In addition, many vehicles also have fog lights as standard equipment or popular options, fog lights are generally installed in a lower position on the car, and therefore very vulnerable to stone damage, in its maintenance, in addition to checking the lighting system itself, projector led light cracks should not be ignored.
