First metal wire, which heats up and blows out steam

Actually, the thin red or brown lines visible on the rear mirror of the car are defogger or defroster grid lines. These are thin metal wires, which, in cold or rainy weather, remove steam, fog or snow from the glass to make the rear clear and this improves rear visibility while driving. While driving a car, as much as the eyes remain ahead, they also remain behind with the help of the inside rear view mirror. In such a situation, it is important for the driver to have a clear view of the rear.

helpful in preventing accidents

When we switch on the rear defogger in the car, these wires heat up and evaporate the moisture accumulated on the glass. Their color is often red or copper, so that they are easily visible from a distance. During cold or rainy season, steam often accumulates on the rear glass and if it is not cleaned, the rear view is not visible and in such a situation the risk of a road accident increases. In such a situation, fog is eliminated with the help of these lines by turning on the rear defogger. This is a very important safety feature for the car, which is seen in almost every new car these days.

Ease of parking also

Let us tell you that if everything is clearly visible from the rear mirror, then reverse parking also becomes very easy. The defogger clears the fog, allowing you to park safely with the help of the reverse camera or mirrors. In a car without defogger, the driver often has to stop and clean the windshield with a cloth, which is a difficult task. In an area where it is cold for most of the year, a rear defogger seems essential. In such a situation, if you go to buy a new car and your budget is very low, still you must check whether the car has a defogger in the rear windshield or not.
