What does VLT Mean according to Illinois State Law
The percentage of light that a window tint film allows to pass through your car windows is called the VLT (Visible Light Transmission), and each state has different legal allowable limits. The amount of light allowed to pass through your film and glass in Illinois is very specific to the state and is different for Passenger Vehicles and Multi-Purpose Vehicles.
A HIGHER VLT means that more light is allowed to pass through the window tint film.
Example: a 75% tint will allow 75% of the light to pass through whereas a 5% tint will only allow 5% of the light to pass through, making the 5% tint a much darker film.
