After you remove the bezel's three screws,
removing the headlight assembly is not difficult if you can find the five #30 torx screws. They are some what hidden behind the headlight assembly and hold the black ring to the chassis and also holds the lamp assembly.
I used a 1/4 inch extension and tape the torx driver to the socket so it would not come apart. There are three screws on top at the nine, twelve and one o'clock positions. The one at one o'clock is the hardest to find. The bonnet must be up to get a good fix on it and remove. The bottom ones are easy and at the five and seven o'clock position.
The adjuster cable must be separated from the yellow plastic holder in the engine compartment. This is much easier with two people although I separated them, alone. with difficulty. A word of caution after you remove the screws you will see the adjuster cables attached to the casing of the headlamp assembly. Don't try to uncouple at that point as the case still won't uncouple. It is better and easier to remove the yellow plastic part. At this point you are ready to remove the headlight assembly.
