What does VLT Mean according to California 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 California 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.

California Window Tint Medical Exemption References
California State Law allows window tint medical exemptions to be given to vehicle owners. To file for a medical exemption in California you will need a letter stating the medical necessity for darker window tints that is signed by a licensed physician. If your physician determines it is in your best interest to be exempt from California Window Tint Laws for diseases and disorders, you can file an exemption.
You are required to carry the physical medical exemption certification with you at all times in your vehicle if you have window tint installed on the side windows in the front seat or on the windshield.
It is also stated in the law that the window tint installed according to these medical exemptions shall not be used during darkness. This seems to imply that your car may be rendered useless or at least illegal to drive at night. Only clear, colorless, and transparent film may be applied to your windshield and front windows according to the California window tint medical exemption rules. If an alternative type of window tint film is found to have been applied to the vehicle, authorities may require you to remove the tint.
