In a lot of states, my understanding is that the tickets generated only count as a civil fine, with no corresponding points attached, so it's equivalent to an equipment/non-moving violation. I'm almost positive that the red light camera fines in NY operate this way. California may be different, but I'd be surprised.

You may want to retain an attorney anyways. If you had partially entered the intersection just prior to the light turning red, then you may not be in violation. The camera, of course, snapped your pic in the intersection, but if you started the turn prior, then you didn't break the law. It's that way in NY, anyways, so it may be worth it to check CA's laws to see if there's a similar exemption there. A good traffic attorney may also know if the yellow light times are shortened at that particular intersection (common with red light cameras, unfortunately). If they're shorter than what is mandated federally, than you may have a case.
