Tint Laws
In the United States, each state regulates window film use on automobiles. Most laws stipulate the amount of visible light transmission (VLT) that pass through the windows. The higher the percentage of VLT; the lighter the film. A 70 percent window film is nearly clear to the naked eye, while a 15 percent window film would appear nearly black from the exterior and make it difficult to see through the glass. Consumers should be familiar with local laws that govern vehicle window films before making a decision on installation.
