I need to get a closer look at my headlight assembly, but there is a plastic shroud/guard covering it. It's attached with little plastic buttons.
Put a screwdriver in the slot on the side and gently raise up the center section. You may need to work it from both sides. Once the center section is raised, it should look something like this:
Once the center section is raised, grab it from the base (or put your screwdriver under the base) and wiggle it free.
