The only thing you can do is plead not guilty and schedule your day in court. Have both door glass windows re-tinted with 30% tint (or lighter). Bring your car and your receipt to court. They may actually have the officer go out and check your car (but usually presenting your receipt to the judge is enough) and they will dismiss your ticket. A big hassle I know . . . I've been there / done that many times getting hassled because the front door glass windows on my fleet of Chrysler SRT8s (airport transportation business) was one shade darker than legal. I finally "gave in" and had all of the cars in my fleet re-tinted with the "legal" darkness of tint film.
