There are many such features inside the car, whose purpose is not only convenience but also safety. One of these features is the thin lines made on the rear glass of the car, which is called the 'rear defogger lines'. Often people ignore them thinking they are a normal design, but these lines are made with special technology and play a very important role.

This is the work of a defogger.
Actually, in cold or rainy seasons, fog or water droplets freeze on the rear glass of the car, due to which the rear view becomes blurred and the driver is unable to see anything properly. In such a situation, these defogger lines generate heat and clear the moisture accumulated on the glass surface, due to which the rear view becomes clear.

The defogger line is activated by the switch.
This feature is not active all the time. For this, a separate switch is provided in the car, which the driver turns on as per the need. After turning on the switch, mild electricity flows through these lines, due to which the moisture or fog accumulated on the glass is removed.

This feature is very helpful, especially in winter and rainy season and reduces the chances of accidents. This is a very important technology in terms of car safety and visibility, which all drivers should know and use.
