Front doors must allow more than 25% net of light in. This means that the window film's Visible Light Transmission (VLT) + the natural glass must be above 25%. Back side windows and rear windows may have any darkness if the vehicle is equipped with side mirrors. Texas Law requires us to apply a compliance sticker on the bottom corner of the driver door window to notify law enforcement & inspectors of the film compliance. Sticker MUST be present regardless of the film's VLT. If customer opts out of having this placed, Texas Tint Masters will NOT be held responsible for citations.
