Replace burned out bulbs how simple exterior lighting maintenance

Check the exterior lighting bulbs burn out failure is an extremely quick and simple task. However,

maintenance of vehicle lamps on a comprehensive system is not so simple.

Timely maintenance of the vehicle lighting is essential for motorists, because it affects not only

driving comfort, but also directly related to traffic safety. Usually before getting to remind the

owner is difficult to realize that headlights, taillights, turn lights or parking lights has been

unable to work properly. Incidentally, replace burned out bulbs work is very simple, the cost is

lower than its DIY repair station for charging standard lighting system maintenance.

More often, the fault must not be limited lights bulbs burn out, or plug socket corrosion damage of

this kind of small problems, often need to take professional diagnostic techniques to analyze the

root cause of the malfunction occurred. Even those low-cost car, its interior and exterior lighting

is also controlled by the host computer; while those luxury cars, their headlights on only three

computers from the control.

If the car is equipped with daytime running lights system DRLs (DaytimeRunningLamps), you must first

understand the working principle of these devices. For example, some daytime running lights system

before the engine is started, the daytime running lights can not be opened; There are daytime

running lights system, if the parking brake has not been canceled, even if the engine has started,

the daytime running lights are still not working properly. If the vehicle is equipped with a light-

controlled light (ie, when the outside light is dim to a certain extent, the system automatically

turns on the headlights with the function), may wish to check the status of a photosensitive from

the weakest to the strongest during the lights work, of course, Do not ignore the check

automatically turn off the timer. If the system is equipped with a timer, set it to the maximum

delay.

If the headlight is damaged, usually similar fixtures to be replaced. Some cars equipped with high-

intensity discharge headlamps HID, high-pressure arc the device through its pre-designed electronic

system to produce high-density discharge generates light. Note that ordinary quartz - halogen bulbs

can not be applied here. Also, before checking headlight lenses for cracks, because although the

surface cracks do not affect the performance of the headlights illuminated, but the moisture will

penetrate cracks along the lamps, which inevitably will reduce lamp life.

Calibration headlight illumination direction should also be included in the list of maintenance

items, because in order to ensure maximum safety of motorists driving, headlights must be able to

provide good lighting for the driving of the vehicle forward.

plate light, showing the wide lights, parking lights, down lights and brake lights (including the

middle brake light CHMSL) and so on. In addition, many vehicles will be fog lights as standard

equipment or popular optional parts, fog lights usually installed in the car a lower position, and

therefore vulnerable to stone damage, while its maintenance, in addition to checking the lighting

system itself, the headlight lens crack should not be overlooked.
