With car popularity, comes the modding scene that doesn't care about laws or safety. Every time someone posts pictures about their headlight, taillight, or windshield tints, they claim they still have full visibility without actually testing % visibility in all conditions (day/night + fog, rain, snow, etc) or correct light patterns
Hope you are never involved in an accident. If you ever get in an accident, your insurance may deny you coverage or hold you liable due to reduced headlight, taillight, and/or windshield visibility. If you're dealing with another insurance company, they might actually sue you (and your insurance might not back you) if you were the cause of the accident (no matter if it was because of the tints themselves). If someone hit your parked car from the rear, they could claim that they couldn't see the reflectors of your taillights due to the tinting.
OP, you should read this thread:
To the people that lambasted me for tinting headlights (and windshield)... : teslamotors
On top of all that, now you are a prime target for cops. Good luck doing any speed over the speed limit, they're going to nail you for everything.
I can already guess what a cop will nail you with:
- Tinted headlights
- Tinted taillights
- Tinted windshield
- Missing front plate
- Missing front HOV lane sticker (and rear left side sticker also if you dont have it on)
