Headlights / lights fogging up on the vehicle? This helps!

What do you do with so-called fogging on headlights and other lights? The phenomenon of fogging - So from fogging of the main headlights or other lights on the vehicle turning on - occurs mainly in the Winter, on. But even after visiting the car wash, while cooling down the engine compartment in a cool environment, in generally wet weather and when there are high temperature differences between the headlights and the environment, you can often see the phenomenon. But moisture means one Lack? Can you continue like this or you have to do it immediately eliminates be? We have the answers. The phenomenon occurs current vehicles even stepping up as they are almost all over clear cover plates feature. This is why the inner fitting is much easier to see than on old vehicles with corrugated and barely transparent lenses. But even if some moisture gets into the headlight, don't worry about rust. Today's reflectors are all made of plastic and the electronic components are usually too adequately protected.

Why do headlights or lights fog up?

Headlights are not tight completed but have one ventilation system. Moisture can penetrate through this, but it can also come out again. And it is necessary because of that Pressure equalization inside the headlight.

However, if the moisture cannot escape to the outside as quickly, then there is fog visible. However, there is no need to worry that this is a real one Lack could act, because the moisture evaporates when the light is switched on at the latest. Even if they fog up again when the headlights are switched off, that still does not indicate a defect. Because when the lights cool down, the moisture in the air is literally sucked in. The spook should be over when the weather is dry at the latest.

What is the fault of the fogged headlight?

If the light source of the vehicle is correct Waterdrop form, then one should look for the cause. Possible reasons can be the following:

• longer journeys in the rain
• Cracks on the seals
• Cracks in the cover
• high humidity or large temperature differences
• fallen off ventilation rubbers
• Cracks in the housing
• Leaky housing or damaged seal due to overheating when using more powerful lamps that are not intended / approved for the type

When is a visit to the workshop necessary?

If water has penetrated that can no longer find its way outside on its own, it is the way to the workshop necessary. The affected headlights or lights must be removed and carefully to be dried. This can be done with so-called "Silica pads“That you know from the packaging of leather goods or electrical goods, or by blowing it in of warm air, happen. It is important to ensure that no water stains stay behind, because this would significantly reduce the light output. The expansion is often very complex and can sometimes the complete dismantling make the front of the vehicle necessary.

After Drying and reinstallation the headlight, this must be to be set again. This is important to get the correct headlight range and not to dazzle oncoming traffic. By the way, the reflector or the glass of the headlight must be replacedwhen this tired. Even if it only happens partially. Often it is only possible to replace the entire headlight. Likewise also belong colored light bulbs (e.g. coated flashing lights) replaced when the coating flakes off.

Nothing against a permanent one Moisture precipitation Doing so on the inside of the lens is not a good idea. Because if the moisture stays in the headlights or in the lights for longer, the seals, covers and reflectors suffer, as already mentioned. The resulting consequences not only make the vehicle look older, but also make it inoperable more quickly.
