Since it only takes a tiny amount of voltage to illuminate an LED what you are seeing is normal. The tiny bit of voltage present on your trailer wiring harness is illuminating your LEDs slightly.

What you can do is install load resistors on the circuits of your trailer that are dimly lit and the problem will go away. For that you would want the part # DI34ZR.

My contact at Curt stated that the small amount of power will not drain the vehicle battery since it is much a minute amount of power. You can also just unplug the trailer from the tow vehicle when parked if you are worried about draining the battery.
