In the video, a person is seen applying a clear film to the rear light of a black car. The person is holding the film with both hands and carefully aligns it with the shape of the light. The film appears to be a type of protective covering, possibly for the light itself. The person smooths out the film to ensure it adheres properly to the surface of the light. The car is parked in a garage, and the background shows various items such as shelves with boxes and other car parts.
