Replying to Help me NS to get out of running a red light ticket...

Hey NS! I need some help and you guys have helped me a lot out in the past with advice.

I just got pulled over tonight for running a red light. I was driving, looked over, said something to someone, and looked back and the light was yellow. I was hesitant to slam on the breaks because I had my soon to be girl friend next to me (asked her out tonight and she said yes) because I didn't want her to fly forward, so I decided to coast through it while it was yellow.

According to the cop, it turned red when I was half way through the intersection (I never saw it turn red), so he pulled me over and gave me a ticket.

I'm 17 and have been driving for about 9 months now, and I'm definitely going to try to take this to court. But what should I say? What should I expect? I'm super frustrated and angry about the whole thing...
Thanks NS! You guys are the best, hopefully someone can help me out.
