The "is car headlamp eyes", its technical condition quality directly affects the safety of driving at night, in use must cause enough attention.

1, the use of headlamp

Use headlamps, should note:

Keep headlamps have good sealing, to prevent dust and moisture intrusion makes reflector rust. If discover the light distribution between the glass and mirrors the gasket seal bad or match light glass damaged, should change in time.

Keep reflector clean. Replacement bulbs or match light glass mirror mirror fingers don't touch, lest the sweat be soiled or greasy fingers and make its pollution mirror reflection efficiency, reduce lose luster. Mirror, mirror when there is some dirt on application compressed air blowing off, unfavorable cloth or brush wipe, lest destroy mirror luster; Don't blow with mouth, lest saliva splashed mirror. When mirror mirror can have grease according to the following ways to clear: for plating lead reflector, usable dip in the clean cotton yarn, alcohol by reflector center a spiral direction to external wiped clean; For plating silver reflector, its coating can't wipe, can use hot water to rinse, after waiting for air can refitted use.

Keep wiring is good. All wiring, take a wire should be stable contact, each may not have any virtual meet or tweeters, otherwise the phenomenon oxidation corrosion will cause headlamps not bright or light emitting slight.

Keep assembly correct. Generally in light distribution have positioning device or glass with L/R and mark, refitted headlamp light distribution should be paid attention to when the installation position of glass equipped wrong, not shall not be inverted or askew, should maintain edges, prevent its loose face vertical displacement. And should be regularly check and adjust light beams, to ensure that accords with a requirement, irradiation range headlamp uniform on both sides headlamps beam. In addition, when headlamps filament damage shall timely replacing the same specification of the bulb.

2, headlamps adjustment

Under normal circumstances, both sides headlamps beam should not scattered or fluctuation dislocation, also should not point-blank ahead, lest make the head-on car drivers to dazzle insufficient lighting intensity and car nearby. However, due to various reasons, such as replacement bulbs, lamp holder and mirrors adjustment screws loose etc, can cause axis snaking, so must check and adjustment.

According to the regulations will tyre pressure enough, the car is in no-load condition and parked flat court, ensure body level of integrity, car is the screen or AD hoc wall, make the headlamp with wall or light distribution glass screen the distance between keep 10m.

Tighten headlamps screws, wipe with light glass.

Measure the left and right of the headlamp from ground height chalk h, in wall or screen height is 80% mark a horizontal h.

Picture 2 the ZhongChuiXian, respectively with the car left, right, that are headlamp and 80% ZhongChuiXian 2 in the intersection of F1, h horizontal axis focus is that the headlamp F2.

Light switch, observe closed whether light beam center in F1 or F2 point. If any deviation, should adjust.

Adjust, can be turned around the upper and lower headlamp, or rotating headlamp adjustment screws, light body up, down, left, right of adjustment.

If do not have the above inspection condition, also can use the following simple method inspection: the night car in the straight and flat roads, light switch, among close with become light switch, the headlamp is only 2 cover one headlamps, check whether another headlamp beam irradiation in front of pavement in about as central, such as a deviation should be adjustment. And then, by the same method check and adjustment another headlamps.

3, headlamps trouble shooting

Headlamps not bright

If the speaker can ring, the only other outside except headlamp can normal shiny, lights that fault may be headlamps circuit breakers, tweeters fall loose, filament.Application wire short-circuited method, and give out breakers parts meet or replacement. Heavy

Without the or no in the headlamps

If headlamps only high beam without the, or only the without high beam, explain the fault may be is a double wire headlamp filament bulb already burned broken, far, the circuit exists, become light switch damage PVB etc. Usable wire short-circuited method from getting examine optical switch to the circuit, the filament evacuated after the failure parts.

2 only the brightness of the headlamp is different

If connected headlamps, whether in or the after only one, are lighter, and light lamps dim the lights, the other side headlamps the main reason: lights dim side of the headlamp lamp holder and lamp bulb and chandelier room, with frame, fixtures between between poor contact or corrosion, make contact resistance increases; Lights dim side of the mirror of headlamp oxidation and plot a occurred dust. Usable wire short-circuited method, and the bounderies failure positions quickly shall be excluded.

Headlamps suddenly out of control

If headlamps high beam suddenly dark not focusing on the high beam, dashboard light changing switch hit when the whole vehicle headlamps, still shine light suddenly out of control, explain the filament has been broken, and burn with high beam filament series together, then should be replaced headlamps bulbs.

Headlamps bulb often burn out

Headlamps bulb often burn out the main reason is: headlamps fixtures are loose; Alternator regulator fails, output voltage is exorbitant, causing filament voltage exorbitant and burn off. Then, should tighten headlamps fixtures, correctly adjusting regulator.
