Haha, cops should be able to "mark" the lights with problems by banging them with their maglites. If you are dumb enough to smoke visual aids, you deserve a few thousand dollar bill.
It is interesting reading the wording around smoked headlights/taillights. The last time I read the laws, they were legal but you had to pull the smoked covers off at night. I don't know a single person with smoked lights that has ever taken them off. I can't remember what the rules were for indicators.
Well if the vehicle isn't legal to drive then they can tow it, fine the driver, pull the plates, and not permit it for road use until it's back in operable state. I'd say that does the job nicely.
