There is no magic formula for beating a red light ticket, contrary to what those websites would like you to believe. If there is a photo of you actually driving the car, then you can't say it was someone else. The photos will also usually show you in the intersection with the light red. Unless you feel you were actually innocent or there is some defense that you raised in your initial defense that you think has merit, you should tell the judge that you want traffic school and tell the judge about your finances (bring proof if possible) and see if you can get any leniency. Usually, they will knock a little bit off the fine if you can demonstrate financial hardship.
Red light tickets come with a great deal of controversy regarding their legality, etc. To answer your question, they can be won at trial -but they cab be tough. Some judges will offer lower fines if you plead guilty and request it right away. Some courts might even allow you to do community service. They are expensive tickets. Don't forget to ask for traffic school if you are eligible.
