You probably travel by car everyday. If you do not travel everyday, then at least you must have seen cars around you everyday. You must have often seen that many thin lines are made on the rear glass of luxury vehicles. However, it is not only on luxury vehicles, but it can also be seen on common vehicles. But have you ever thought why this happens? Why do companies make these lines on the rear glass of vehicles? Today in this article, we will give you the answers related to these questions.
what are these lines called
Actually, these lines made on the rear mirror of the vehicles are called defogger lines. That is, if you were still thinking that the lines made on the rear mirror of the vehicles are just a design, then you are wrong. Actually, these lines are made of metal. Excellent engineering work has been done in these lines.
what is their job
The work of these lines is understood in rain or fog. Actually, this defogger line does not allow raindrops and fog to accumulate on the rear glass of the vehicle, due to which the driver behind the wheel can see everything clearly behind. However, these lines do not always work. For this, there is a switch in the vehicle, which is used by the driver when he needs these defogger lines.
how do these lines work
We have already told you that these defogger lines are completely made of metal and their switch is located near the driver in the vehicle itself. In fact, when the driver cannot see anything from the rear mirror, he turns on the defogger lines. As soon as these are started, these metal lines start heating up and the rear glass of the vehicle also dries up the fog or rain drops and the driver can see everything clearly.
