Open the hood, and using a 7mm socket remove the long headlamp jackscrew, 2nd from left. Grasp the headlight assembly on the upper inboard and lower outboard corners and wiggle and pull very firmly outward to disengage the 3 ball stud alignment posts from their sockets (be cautious of the sharp edges of the grille and fender areas surrounding the headlamp.
It does need a very stong pull but be careful it will come away quickly.
