Current Uk Law with regards to the application of window films to vehicles
THE LAW
The legal position is that the front side windows on all cars must allow 70% of light to pass through them. That figure also applies to the windscreens of cars first used before April 1985; any car first used from then onwards has to let 75% of light through the windscreen.

This means that most vehicles will have around 64% to 68% factory fitted glass so the application of window films will make this vehicle ilegal
50% film will read from 37-32% on most modern cars
35% film will read from 23-18% on most modern cars
20% film will read from 11-7% on most modern cars
5% limo just manages 0.3% on anything.........its dark!
