LED lights and Electric brake STRANGE NOISE

Sound to me like it is wired in incorrectly, but not having a circuit diagram or a clearer description of how you have wired them in it is difficult to know for sure.
There should virtually be no cross connection between the tail light circuit and the electric brake circuit.Only the stop light wire near your brake pedal should be connected to the brake circuit via the controller. The resistor you mention should be fitted in the tail light circuit on the trailer only, and definitely not the brake circuit. But then I have not used LED tail lights as yet, but I have set LEDs up as dash lights

You mention that the red and white wire are used, the red is for the brake light and should not be used to activate the brake itself the blue wire from the controller is used for the brake magnets ,the white is the earth for the whole trailer, if you have used the red for your brake you may have a poor earth in the cars tail lights but still need to wire correctly.
