you have to get the bumper off to get the headlight out as there is a bolt under the bumper it was left out on mine
the best way to get the fog light out
is there is 5 screws 2 in front of the wheel under the wheel arch and 3 under the front of the bumper get them out and the plastic wheel arch can be pulled back to get at the fog light there is also a 10mm plastic nut that needs to be got off
you may need to jack up the car
