What are legalities of tinting/restricting light flow on the windscreen?
Specifically in UK vs the rest of Europe.
I'm researching an idea of covering entire screen with around 87% transparency (13% of light blocked, visual equivalen to another layer of clear glass) projector film.
Possibly hohofilm, example below:
Technicalities leave to me.
I'm asking about legalities at this stage.
Thank you.
