My fog light assembly has been knocked out of the socket. How do I re-attach it?

What is your question?

There seems to be no damage to the brackets that hold the fog light. From what I understand, you access the fog light by accessing the light from the guard in front of the wheel. Is it as simple as getting nails and screwing the light back into place? If so, where do I get these nails? Affirmation and specifics would be great.
