Do you have a clear understanding of the maintenance method of LED lights?

This is a very quick and easy job to check for burned out LED lights. However, system maintenance for exterior lights is not that simple. Timely maintenance of exterior lights is very important for drivers, because it not only affects the comfort of driving, but also directly affects the reliability of driving. Oftentimes, it is difficult for a car owner to realize that the headlights, taillights, turn signals, or parking lights are no longer working properly until they are alerted. By the way, the job of replacing a burned-out light bulb is very simple, and the cost of DIY is less than the cost of maintenance of the maintenance station lighting system.

Often, bulb failures aren't limited to minor issues such as a burnt bulb, corroded sockets, or damaged plugs. Professional diagnostic techniques are often required to analyze the root cause of the failure.

If your car is equipped with DRLs, you must first understand how these devices work. For example, some daytime running lights cannot be turned on until the engine is started; there are also some daytime running lights. If the parking brake is not released, the daytime running lights will not work properly even if the engine is started. If the vehicle is equipped with light-controlled lights (i.e., the system has the ability to automatically turn on the headlights when the outside lights dim to a certain level), you may want to check the operation of the lights during a weak-to-strong photosensitivity process. Of course, don't ignore the automatic shutdown timer check. If the system is equipped with a timer, set it to the maximum delay.

While grabbing the keys, don't forget to check other light systems such as turn signals, license plate lights, side marker lights, parking lights, reversing lights, and brake lights (including the middle and high brake lights CHMSL). In addition, many vehicles also use fog lamps as standard equipment or as a common option. Fog lights are usually mounted low on the vehicle and are therefore vulnerable to damage from rocks. During maintenance, in addition to checking the lighting system itself, cracks in the lamps should not be ignored.
