Just done mine now, passenger side (02 mondeo 2Litre Ghia). Remove the plastic grille at the front by removing the two half turn plastic clips. Then remove the hex head screw on the right hand side at the top of the headlight assy. Then remove the two T30 screws on the left of the headlight assy, about halfway down the thing. There is a plastic bracket in the way of the lower one, but ease the rubber fastener out and this will swing out the way. Partially lift out the headlight assy and pause to remove the wiring clip, (press down on its serrations) Lift headlight out and turn it over on a soft surface, face down. Remove the rear plastic assembly by undoing the clips and hinge the plate open. This reveals the bulbs. Unclip the plug on the back of the bulb affected. Using thin pliers, undo the wire holding clip and away comes the bulb. NOTE don't touch bulb glass, use a clean cloth. Bulb has a set insertion way with flats and serrations, rotate it carefully till it seats. Reverse the whole procedure to replace and the screws go back in the same place so the headlamp adjustment shouldn't move although a quick visit to any garage will align your lights. My mate at work was charged £65 for the bulb change at the Ford garage. Good luck y'all, Micky the Cat (hope my technical author training was easy to folllow)
