If this is your first offense the judge will most likly reduce it or even drop it. But if you make waves by filing a complaint your screwed, with the judge and the cops.
Just go to court and play nice. The spotlight is for his own saftey. He does not know that you may have a gun under the seat and could come out shooting after he gives you the ticket.
Everytime I have been pulled over they turn off the spotlight as soon as your car is moving.
If you file a complaint for that, your going to be pulled over for every little thing.
