Sorry this is best pic I can get

Hi I was wondering if anyone could help I have a set of afterburner lights,on the inside of these lights where the wires are they are attached to a little black box where the wires go into like a control unit but this has been damaged by water and has made lights stop on the left rear and can't find where to get a replacement without buying a new set of lights again or does anyone know what that part is called or know what I'm talking about lol
