    Actually the brake light worked properly without the controller as demonstrated in the picture above .... the brighter light is without connecting to controller .... the light dimmed once it is connected to controller and that is where I am lost .... my only guess at the moment is probably...

    The connections were made as you described except that the 12V used to power the brake light is not from the same 72v lithium battery ....
