I wish I knew what the part was...it's not the headlight assembly but the little square light that sits below...cracked it with a parking median that I did not notice was "in front" of me...have no idea what the name of it is, but would love to replace at a reasonable price, if there's one out there sitting around...

 

I believe you're referring to the fog light. They come up for sale from time to time here on the Forum.
