The best thing you can do is fix the tint and just say that you did not know the limit. If you try and bullshit the judge and officer will know.
If you lie in court you will fall flat on your face and look like a dick in front of the judge. You gotta remember these cops go in front of these judges all the time and they have a working relationship, YOU DoNT.
If you change the tint to what is legal you will show that you are willing to work with them in fixing the situation and not trying to make things harder on yourself.
