Scott, when I had this it was a combination of the Allen screw on the bezel being a bit loose and the bezel itself not sitting snugly. A couple of bits of foam to pad the bezel and making sure its clipped on correctly and tight sorted mine out.
Edit; just thought, if it's the whole headlight that is rattling about then some careful tightening of the securing nuts might sort it out, but might be best to take the bezel and lens off to have a look inside first.
