As stated above he cant do anything to you. He didnt pull you over then. Therefore he cant give you a ticket after the fact. He has none of your personal information and if they do try to give you crap say someone else had your car that day... Granted he could pull you over and give you a ticket for say 5 over if you are doing it to be a dick or if you have a light out could issue that.
That being said you get what you get you did blow the sign lol
