But it can't protect from the visible light that mostly penetrates through the window and gets absorbed by the objects inside the car. The visible light that passes into the interior through the windshield is converted into the infrared light which, in its turn, is blocked by the glass and gets trapped inside, heating up the interior. [4]
The light normally appears when the vehicle ignition is turned on, but the engine is not running, as it detects no oil pressure due to the oil pump not operating (the oil pump is powered off the crankshaft, so only operates when the engine is running). It normally turns off a few seconds after engine start as the oil pump starts working and ...
The Sun appeared to rise two weeks earlier than expected; the real Sun was still visible below the horizon, but its light rays followed the curvature of Earth. This effect is often called a Novaya Zemlya mirage. For every 111.12 kilometres (69.05 mi) that light rays travel parallel to Earth's surface, the Sun will appear 1° higher on the horizon.
Diagram showing displacement of the Sun's image at sunrise and sunset Comparison of inferior and superior mirages due to differing air refractive indices, n. Atmospheric refraction is the deviation of light or other electromagnetic wave from a straight line as it passes through the atmosphere due to the variation in air density as a function of height.

Unlike window film, privacy glass is a pigment within the glass that is installed during the manufacturing process. There is no way to remove the tint from the glass except to replace the glass with untinted glass. The only alternative to getting the same benefits of window film is to install window film over the factory tint.
Quarter glass is also sometimes called a valence window. [2] This window may be set on hinges and is then also known as a vent window, wing window, wing vent window, or a fly window. Most often found on older vehicles on the front doors, it is a small roughly triangular glass in front of and separate from the main window that rotates inward ...
Despite its origin as a utilitarian safety warning, the phrase has become a well known catch phrase that has been used for many other purposes. These include books, [2] films (including non-English ones), [b] cartoons, [c] songs, [d] music albums, [e] and other contexts.
Resistive-heat defoggers are usually equipped with an automatic timer to operate for a set time period of 10 to 15 minutes before switching off. This is because most defogging is achieved within that timeframe, after which the vehicle's heater has usually brought the interior of the vehicle to a warm enough temperature that the fog does not recur.
