Checking a light bulb for burnout is an extremely quick and easy job, but it’s not that simple to perform a comprehensive and systematic maintenance on exterior lights. Timely maintenance of exterior lighting is crucial for drivers, because it not only affects the comfort of driving, but also directly affects the safety of driving. It is often difficult for a car owner to realize that the headlights, taillights, turn signals or parking lights are not working properly until they are alerted. By the way, replacing a burned-out bulb is easy, and the DIY cost is lower than what a repair shop charges for lighting system maintenance.
In more cases, the failure of car lights is not limited to such minor problems as burnt bulbs, rusted sockets or damaged plugs. Professional diagnostic techniques are often required to analyze the root cause of the failure. Even those lower-priced cars have interior and exterior lighting controlled by the main computer. And those luxury cars, their headlights alone are controlled by 3 computers.
If the car is equipped with daytime running lights DRL, you must first understand how these devices work. For example, some daytime running lights cannot be turned on before the engine is started; some daytime running lights, if the parking brake has not been released, even if the engine has been started, the daytime running lights still cannot work properly. If the vehicle is equipped with a light control system, that is, when the outside light is dim to a certain extent, the system has the function of automatically turning on the headlights. Check out how the lights work as the light sensitivity goes from weakest to strongest, and don’t neglect to check the auto-off 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 (HIDs), which generate a high-density light source through high-voltage arc discharges generated by its pre-engineered 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 can penetrate into the lamp along the cracks, which will inevitably reduce the life of the bulb.
The alignment 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.
In addition to grasping the key, do not forget to check other light systems, such as turn signals, license plate lights, position lights, parking lights, reversing lights and brake lights.
In addition, many vehicles also have fog lights as standard equipment or a popular option. Fog lights are generally installed in a low position on the car, so they are highly susceptible to damage from rocks. When maintaining them, in addition to checking the lighting system In addition to itself, the cracks in the headlights should not be ignored.
