Some drivers have to deal with such a serious problem as fading headlights. The most annoying thing is that they cannot be thrown out, as the moisture is inside. Why it happens?

Why sweats the headlight

Let's start with the fact that there should be no moisture in the headlight block, even in minimal quantity. Consequently, the presence of condensate in it speaks of water getting inside. There may be many reasons for this.

wrong geometry of headlights

The most common problem is the wrong body geometry - the car was initially incorrectly assembled on the conveyor, because of which there was a small gap between the individual components of the headlight, through which water falls inside. Although it should be noted that today new cars no longer have such shortcomings. In particular, most of the Chinese cars, which previously complain their owners, achieved this level of quality when some production marriages could not be a speech. A bright example can serve any car brand Lifan, as for example, Breez or X60.

depressurization after the accident

Even minor damage to the front of the car during the accident, as a rule, it is adversely reflected in the headlight state. And even if the headlights were not broken, the chance of the fact that their design was not broken, it would be minimal. In addition, when splitting glass or other headlight element, they are often repaired, instead of replacing. And the repair of plastic or glass materials involves the use of simple sealant. Its properties are enough for the first time, but after a few years the sealant will completely lose its original characteristics, which is why the tightness of the headlight will disappear.

cracks on glass

The appearance on the glass even microscopic cracks entails moisture penetration, as a result of which the headlight fades. A microcrack may appear on the glass, which is difficult to notice with the naked eye, but the wet air and the headlight will be tightened.

the output of the hydrocorographic

Specific reason, but quite possible. The essence is that in some headlights there are hydraulic proofreaders. In other words, you turn the handle on the instrument panel, the pressure increases and the light level increases, or falls if necessary. However, often, especially on domestic cars, they fail, the liquid flows into the headlight, which is why fogging occurs.

The headlights sweat that threatens the car

If it is not possible to eliminate the cause of the periodic appearance of moisture inside the headlight, this may entail not very good consequences:

• Detection of visibility.When the light beam passes through the condensate layer, it dissipates and refracts, and this is substantially affecting the level of road illumination. The modified optical characteristics of the headlights, in turn, lead not only to discomfort during driving, and are able to provoke an emergency.
• Reducing the life of the lamps.Functioning in high humidity conditions significantly reduces the life of the light bulbs even in the highest quality lighting equipment.
• The destruction of metal surfaces, in particular the reflector.If the moisture is constantly in the headlamp, this leads to rust on contacting metal parts.
• Loss of electrical connectors.Since moisture has a negative impact on contacts, it entails oxidation, which can cause a complete or partial output of the wiring of the car.

What to do if the headlights sweat because of the wrong design

If you notice that the headlights on your car are fisted, the first thing you need to do is include them.

The heat that will be released will heat the inner space of the headlamp than dries off. But remember that xenon lamps highlight heat is much smaller than halogen. Therefore, if the headlights in your car are equipped with xenon lamps, such a procedure is likely to not give the result.

Some drivers recommend applying a special composition - silica gel. Note that packages with this composition can be often seen in shoe boxes.

However, this method has a reverse side. Silica gel swells over time, therefore, its mass increases, which can entail damage to the headlights from the inside. Therefore, this method can be used only as a temporary measure, but should not be delayed with the elimination of the very cause of headlights.

What to do if the headlight sweats due to damage in collision

First of all, dismantle the headlight and dry it.

After drying, follow the headlights on the presence of cracks or other damage. If the chips and cracks are absent, but the moisture all appears exactly, it is necessary to seal all the joints of the housing and glass - this is done with a sealant, preferably colorless.

So you can remove all microcracks. Look at the fitting of the lamp to the case. It must necessarily have a gasket, sometimes plastic, sometimes rubber. If the gasket is missing, it is because of this that moisture can be delayed.

What to do if the headlight sweats because of microcracks on the glass

If you find a crack on the headlight housing, you can try to eliminate it on your own. It will not work out to do with a tape or glue, the best tool for repairing the headlight housing is a special soldering iron designed for plastic. You can also solve the problem with special auto-care. If the glass cracked, ideally it is necessary to replace it, but it is not always sold separately. Buy a headlight is also not an option. Then what to do? If the crack is small, cover the toning film from above, but take the transparent, not dark. She has a sticky base that seals all the cracks, and the glass will not sprawle on.

What to do if the headlight hydro-director failed due to fluid leakage?

As a rule, hydro-correlates of headlights are inappropriate design not subject to repair. Therefore, if the hydro director has failed, it is necessary to replace it with a new set.

Tips Pros: How to find the air suction site on the spotlight?

To accurately determine the location of the air on the spotlight, you need to remove it. This method guarantees one hundred percent result. Pour water into the bathroom and lower the headlight. Look, where bubbles come from - this will be the air suction site.
