Electric window tint is not specifically mentioned as being illegal in India. However, the use of window tint in general is regulated by the Central Motor Vehicles Rules (CMVR), which are overseen by the Ministry of Road Transport and Highways.

The CMVR sets out the permissible limits for the Visible Light Transmission (VLT) of different types of window glass on vehicles. VLT is the amount of visible light that can pass through a window, and is measured as a percentage. In India, the permissible VLT limits for various types of vehicle windows are as follows:

  • Windshield: 70% VLT
  • Front side windows: 50% VLT
  • Rear side windows: 50% VLT
  • Rear windshield: 30% VLT

If the VLT of the window glass is below these limits, it is considered illegal in India. The use of any type of window film or tint that reduces the VLT below the permissible limits is also not allowed. This includes electric window tint, which can be adjusted to reduce the VLT of the window.

The reason for these regulations is to ensure that drivers have adequate visibility while operating their vehicles, and to prevent the use of dark window tints for illegal or criminal activities. It is important for vehicle owners to adhere to these regulations to avoid fines or other legal penalties
