I believe that friends should notice that there is a line of horizontal lines on the rear glass window of their own car，Some are red，Some are white。But if someone asks you what these horizontal lines are used，You may be difficult to answer，Come and talk to friends today: What is the use of the horizontal lines on the car back of the car?

Electric heating Remove seabet mythe fog cream of the rear gear

Winter time，Due to the cold weather in the car，The humid and humid gas exhaled from the human body and the heat generated by the engine gathered together，The temperature inside and outside the carriage is very different，On the way to the car，The humid and humid air in the car is exposed to the cold cars rear window glass，A frost will be knotted in the past，Affecting the driver's sight，Bring hidden dangers to reversing and safe driving。

For this，The manufacturer sets a small interval with even uniform electric heating wires in the expansion of the double -layer glass of the rear window，After passing it on it，can emit calories like an electric furnace，Fast melting frost、evaporate，Makes the rear window glass always transparent and clear。

The keys to start the electric heating wire is located next to the air conditioner and inner circulation buttons，Many car owners have seen this button，But I rarely think about what it is used，It will even mistake it as an internal cycle，and the electric heating wire button should be matched with the frost button，Use together after the car is started，It is best not to exceed 5 minutes each time，Because it is heated for a long time, it is easy to overload the glass，Thus leading to crushing。

Receive radio signals

In addition to electric heating,，Among seabet iothese electric wires，There will be a few rows of car media antenna，Generally on the upper end of the glass，Used to receive radio signals，Because it is arranged in a mesh in the glass，Long life span、Not easy to break、Features of good signal。

The previous car antenna design was on the roof，The efficiency of receiving signals is relatively low，and the effect is not good，Intermittent situations often occur，and these horizontal lines because they are horizontal，Being able to receive signals more stable。

This method of integrating antennas into the glass，The earliest was invented by Henz Linden Mel, a professor at the Federation of the Federation of Munich。Because it is printed on the glass，So it is also called the printing antenna，It is the existing electric heating wire on the rear block，As a signal receiving line。

Both divorce and antenna function, pay attention when using

In short, words，The horizontal line on the back block，Dividence，Also the antenna of the car，It looks，There is no sense of existence，But it ’s really impossible for many functions。
