On the Pilot brake controller # 80550 the red dot appears when you step on the brake pedal or use the manual override WITHOUT a trailer connected. If a trailer is connected and you only get the red dot then the controller is not reading that a trailer is connected. This could be from a dirty or corroded trailer/vehicle side connector, a wiring problem to the brake magnets on the trailer, or a break in the wire from the controller to the vehicle trailer connector. I have included some links on testing and troubleshooting brake controllers for you.
