Not familiar with the 2013 lights. Are these leds inside the headlight housing, or are they easily removed? Like any led, they could be simply changed for a color of choice by replacing the led stack/stick; the hard part would be getting at them.
By law, Ford kept them to the color required by the DOT, but it may have been neet if there was a kit that allowed you to change them like you can with the interior lights ("my color" option). But that would have held Ford liable for allowing folks to break certain DOT laws and requirements.
