I was never sure when I put the tint on but after a while I really do like it. It does conform to MOT regulations, allows full function of rear reflectors, does not affect pattern or brightness and as a result completely road legal. If it wasn't then I wouldn't be using them as I would like to be seen on the roads at night. Everyone is different though and that what makes your car your own. Personally i think it makes the front look more aggressive.
To each his own, mate. And as I said, your car looks stunning at any case. Great work done on it, you truly motivate me to start visually modifying my Leon as well. Any mod I do, whether it is big or small, just makes me a happier man, especially when it's a DIY job.
Have a great day!
