I used a 10mm socket to remove these bolts.

If necessary, it's a good idea to use some type of lubricant (such as silicone) or penetrating oil on these threads because they are prone to corrosion.

I used a large screwdriver to pry against the headlight housing. This caused the hidden plastic stud-and-socket to separate, as shown below.

The lower arrow points to the stud, which is molded into the plastic headlight housing.

To prevent scratching the paint on the bumper, I first pulled on the grill-side of the plastic housing.

Then I pulled on the fender-side of the housing and the entire assembly came out.

Then I disconnected the wires from the light housing.

To remove the head light bulbs, I unscrewed these plastic caps to reach the bulbs inside.

The bulbs were held in place by a retainer clip. The retainer can be removed by squeezing two tabs.

Note On Handling Headlight Bulbs:

Do not touch headlight bulbs with your bare hands, because the oil on your skin can ruin the light bulb. Use a paper towel or tissue to handle the new light bulb.

Once the bulb was replaced, I connected the wiring and turned on the head lights to make sure they all worked.

Then I replaced the headlight housing and re-installed the bolts.
