Every vehicle definitely has various features that are not only used for daily use. However, some also serve as a safety tool in certain situations.
If you notice, some cars have thin lines on the rear window. These lines are called ‘defoggers’ and have an important function when you are driving a car.
For those who still do not know, ‘defoggers’ are lines of electrical filaments that can generate heat if the rear window of your car starts to look blurry due to fog.
According to Top Gear Philippines, the strip is usually very functional for vehicles in cold climates compared to the tropics.
A special button needs to be pressed to activate and deactivate the heating element with a rectangular icon and three wavy arrows.
Interestingly, the windshield of a car is also actually equipped with ‘defoggers’ but it is changed in the form of a hole in the bottom of the mirror because the strip will obstruct the view while driving.
