It sounds like the stoplight circuit wire from the brake controller, (the red wire), isn't connected to a circuit that sees voltage when the brakes are applied. I would check the connection of the red wire to verify that it is connected correctly to the correct circuit. Typically this wire connects to the cold side of the brake pedal light switch.

I also attached an FAQ on brake controller installs plus a video to show you how to troubleshoot your brake controller.
