There are three 10 mm bolts that hold the headlight assembly in.
Two are visible on the front side of the headlight assembly when
the hood is up. The other is below the light assembly where the
back of the light assembly meets the fender. It is accessed from
the front and will require a socket extension.
Once the bolts are removed, gently pull the headlight assembly forward. You will see two long plastic pins on either side of the assembly. Pull the light assembly forward until they are clear of the holes. You should now be able to swing the assembly out far enough to reach the directional bulb socket. Twist the back of the bulb assembly about 45 degrees and then pull the bulb assembly out of the socket. Replace the bad bulb, ensuring that you do not touch the bulb with your bare hands and leave oils behind, which will damage the bulb once it gets hot.
Reassemble in reverse order.
