he issued me a ticket for the plate light.. can he issue me this ticket even though he didnt notice the plate light until I was pulled over?
Yes, a vehicle can be pulled over for fail to signal and then be given a licence plate light offence or BOTH offences could have been issued.
The officer used some discretion, rather than issuing a moving violation offence notice with 2 demerit points, you received an equipment violation with 0 points.
