Car Visible Light Transmission
Introduction
Car visible light transmission (VLT) is the percentage of light that can pass through a car window. It is an important factor to consider when choosing window tint, as it can affect the amount of heat and glare that enters the car, as well as the visibility of the driver and passengers.
Legal Requirements
In most countries, there are legal requirements for car VLT. These requirements vary from state to state, but they typically specify the minimum amount of light that must be able to pass through the windshield, front side windows, and rear windows.
Windshield VLT
The windshield is the most important window in the car, as it provides the driver with the clearest view of the road. For this reason, most states require that the windshield VLT be at least 70%. This means that at least 70% of the light that hits the windshield must be able to pass through it.
Front Side Window VLT
The front side windows are also important for providing the driver with a clear view of the road. However, they are not as important as the windshield, so the VLT requirements for front side windows are typically lower than those for windshields. Most states require that the front side window VLT be at least 35%.
Rear Window VLT
The rear window is not as important for providing the driver with a clear view of the road, so the VLT requirements for rear windows are typically the lowest. Most states require that the rear window VLT be at least 20%.
Factors that Affect VLT
There are a number of factors that can affect the VLT of a car window, including:
* The type of glass: Some types of glass, such as tempered glass, have a lower VLT than others, such as laminated glass.
* The thickness of the glass: The thicker the glass, the lower the VLT.
* The presence of a tint film: A tint film can reduce the VLT of a window by up to 99%.
* The condition of the window: A scratched or damaged window will have a lower VLT than a new window.
Benefits of Tinting Car Windows
There are a number of benefits to tinting car windows, including:
* Reduced heat: Tint film can block up to 99% of the sun’s heat, which can make the car more comfortable in hot weather.
* Reduced glare: Tint film can also reduce glare, which can make it easier to see while driving.
* Increased privacy: Tint film can make it more difficult for people to see into the car, which can provide increased privacy for the driver and passengers.
* Improved safety: Tint film can help to hold the glass together in the event of an accident, which can reduce the risk of injury to the driver and passengers.
Conclusion
Car VLT is an important factor to consider when choosing window tint. By understanding the legal requirements and the factors that affect VLT, you can make an informed decision about the right tint for your car.
