The headlight glass tarnishes easily in the cold. Obviously, this is not the only part of the car that is affected by the change in temperature.

The same problem occurs when you get into the car and start the engine. The windshield fogs up immediately, seeing beyond the glass becomes impossible.
For the interiors the solution is at hand, you turn on the stove and that’s it. For the outside, the situation is slightly different.
But before reaching the solution, it should evaluate the causes. The first could be linked to the capillary effect of the wiring, although it is rare that it has to do with this.
Common causes of fogged headlights
The most common cause, on the other hand, concerns replacement of the light bulb which often happens in the workshop where the rubber plugs may not be closed correctly. To prevent this problem from recurring every time you change the bulb, just use a hair dryer at a not very high temperaturea, which serves to close the cap well and therefore does not let air through.
Another cause could be the humidity that forms insideor, because somehow the air manages to enter and collide with the heat produced by the lamps. Thanks to this heat, however, the condensation goes away and therefore the headlight cleans itself.
Whatever the cause, of course it is important to find the solution, because condensation inside the headlights does nothing but reduce visibility while driving, which can be a big problem when driving in completely dark areas.

How to eliminate the condensation that forms inside the headlights of the car
There are those who think they can use hot water to solve the problem and who somehow provides for the drying of the lighthouse while wasting a lot of time every time it is necessary to use the vehicle. But these days a video was released on YouTube that left everyone speechless.
Show a man who uses a pump with which he sprays some Red Bull on the lighthouse. It is incredible but the condensation goes away practically immediately, without any effort. Many are skeptical and do not believe that this method really works, so if you don’t want to do it this way, there is a fairly common solution that requires disassembly of the entire headlight. It takes more but in theory the problem is solved once and for all.
Then, the electrical part is separated, washed with the neutral detergent and with distilled water. Once dry, a new wet seal is fitted with a silicone spray and that’s it. The problem shouldn’t recur anytime soon.
In any case, just disassemble the headlight, dry it, or use dehumidifying salts or a ball that collects the water vapor. For these purchases you spend around 10 euros, but it is certain that they work.
