Why don't people use light-colored window films?

[Reid]

Light-colored films mainly fail to protect personal privacy, which is why most car owners don't choose them. Here is some relevant information about car window films: 1. Functions: Blocking UV rays, especially during hot summers when sunlight is intense. Films can block a portion of visible light and UV rays, helping to reduce the temperature inside the car; providing anti-explosion functionality; enhancing the privacy of the car. When viewed from outside, the car's interior produces visual reflections, making it harder to see inside clearly. 2. Disadvantages of dark-colored films: While dark-colored films do have an advantage over light-colored ones in terms of privacy protection, in dimly lit environments where visibility is already poor, the additional effect of dark films makes it more difficult to observe the rearview mirror normally. Light-colored films, on the other hand, obviously provide better visibility, making driving more manageable.
