What does VLT Mean?

VLT(Visible Light Transmission) is the light percentage allowed by the window tint film to travel through your car windows. In Wisconsin, there are different legal allowable terms when it comes to window tinting.

In Wisconsin, the amount of light allowed to pass through your window film and glass varies for Passenger vehicles and multi-purpose vehicles. We have decided to break it down for you for the sake of your better understanding. 

The higher the VLT the more amounts of light will be allowed to pass through your window tint film. For instance, a 50% tint will allow only 50% of the light to pass through and a 5% tint will allow only 5% of light to pass through.
