The factory window tint percentage refers to the level of visible light transmission (VLT) allowed through the windows of a vehicle as applied by the manufacturer at the factory. This factory-installed tint is often referred to as “factory tint” or “OEM tint.”

The percentage of visible light transmission indicates how much light is allowed to pass through the window tint. For example, a window with a VLT percentage of 20% allows 20% of visible light to pass through and blocks 80% of visible light.

Factory window tint percentages can vary depending on the vehicle make, model, and trim level. In many cases, the rear windows (such as the rear windshield and rear side windows) may come with a factory tint that provides some level of privacy and UV protection. The front windows (such as the driver and passenger side windows) typically have a higher VLT percentage to ensure adequate visibility and compliance with legal regulations.

The specific factory window tint percentage can vary widely between different vehicle manufacturers and models. It’s essential to check the specifications and options for your specific vehicle to determine the factory window tint percentage. Local regulations may impose restrictions on aftermarket window tinting, so it’s important to verify compliance with applicable laws and regulations when adding additional tint to your vehicle’s windows.
