can I be charged with impersonating a public servant?

my friend who is a firefighter in texas has emergency lights that emergency vehicles use.. he recently took his vehicle back to where he got it due to mechanical issues, I helped him take it back, so all the equipment he had was placed in my truck. he did hook up some of his emergency lights because he might be using my truck for emergencies, i am not a public servant and I was driving down interstate, i accidently turned the lights on and did not know it. I flashed a state trooper. he gave me a ticket for unauthorized use of the lights and said he was going to try to charge me with impersonating an officer, i in NO way would ever do that.. what should I do?
