Have you ever noticed the rear window of most cars to see the thin black lines or firmware color that describe the example on most of the glass is not only an important part but also important in supporting us.

In the visit, the lines are the defogger system (Defogger/Defroster) which will help to eliminate the problem of fog and dew that may stick on the rear window of the car.

The function of the rear window defogger

• Defogging and  preventing dew

In high humidity or cold weather, the rear window often fogs up or dews up, obscuring visibility. Having fog or dew on the window can make it difficult to see behind the car and increase the risk of driving. These lines release heat when the defogger is turned on, which helps to quickly evaporate the fog and dew.

• Increase safety

Clear visibility in all directions is important for driving, especially when driving in inclement weather. The defogger provides the driver with a clear view through the rear window, reducing the chances of an accident.

• Maintain comfort 

In addition to increasing safety, this system also reduces the hassle of wiping the fog or dew off by hand, allowing the driver to focus fully on driving.

How Defogger Lines Work

The lines you see on the rear window are conductive materials such as copper or silver. When the driver turns on the defogger via the control button in the car, an electric current flows through these lines and creates heat. This heat raises the temperature of the glass enough to displace moisture from the surface.

Maintenance Guides

For the defogger to work effectively, avoid using hard or sharp objects to scrape or wipe the rear window, as this can break or damage the lines. If the defogger is not working properly, the associated connections or wiring may need to be checked.

The lines on the rear window of your car are not just decorations, but are part of the technology that helps to increase safety and convenience for the driver. They play an important role in removing fog and dew, making driving in inclement weather smooth and safe. So the next time you see these lines on the rear window of your car, remember to think about their function in making your journey safer!
