Careful car owners must have noticed that there are always "horizontal lines" on the rear windshield of their car, but few people know what the specific role of these "horizontal lines" have. Today, I will answer the "mystery" of the horizontal line on the rear windshield of the vehicle for all car owners and friends.
What is the function of the "horizontal line" on the rear windshield of the car?
Function 1: Electric defrost fog
In winter, the temperature difference between the inside and outside of the car is large, and the rear windows are prone to fog. If it encounters snowy weather, it is easy to accumulate snow, affecting the field of vision. These rear windshields happen to be an resistive wire , which can use high temperatures to dispel mist and frost, ensuring that car friends can also clearly observe the rear conditions through the rear windshield while driving, thereby preventing accidents.
Generally, models with this function will set the buttons of this function next to the air conditioner and internal circulation buttons. When we press this button, we can easily remove frost and mist for our car and gain a clear field of view. However, please note that the time should not be too long when used, it is best to be within 5 minutes, otherwise the glass will not be able to withstand the temperature changes and may break.
Function 2: Receive radio signals
In addition to heating, these mysterious "horizontal lines" on the rear windshield of the car can also receive radio waves. This is because, in addition to the electric heating wires, there are also several rows of vehicle-mounted media antennas. Since they are placed inside the glass, they have the characteristics of long life, not easy to break, and good signal reception. Its principle is the same as the shark fins that often appear on the top of a car, both of which exist as a car component that receives signals and enhances signals.
I believe that after reading this, everyone has a better understanding of the "horizontal line" on the rear windshield of the car. It turns out that it is not a decorative line that everyone usually thinks, but an important car component with real functions.
