My question involves a traffic ticket from the state of: Pennsylvania

This is regarding a ticket I got couple of days when a cop pulled me over for running a Red Light and since I have a clean driving history and I actually was following the traffic and Red light went unnoticed. I was honest to the Cop and hence he gave me a ticket for Obedience to Traffic Control Devices under section 3111 but with remarks as No point and a fine over $100.

The cop asked me to plead guilty or not and sent the fine to the address on the notice.

My question is will it be a problem to my driving license if I plead guilty. What do I need to do? It is my first time and I'm a little worried about this ticket. Please advise and help.
