The head light bulb is replaced from under the hood of the vehicle. Open the hood and look behind the light assembly. There you will see where the sockets are screwed into the assembly. Turn the socket 1/3 turn counter clockwise to remove bulb. Once open remove the old bulb and replace it with the new one. NOTE: Try to avoid touching the glass of the new bulb. The oils from your skin will cause it to go bad sooner.
Let me know if you have any questions.
Here is a picture of the bulb itself:
