What is that white piece thats holding the headlight
Its broken off so the headlight rattles. Whats the part # or name? Any ebay links or amazon links. So i can order it.?

 

Welcome to the forum.
Your photo is a bit too zoomed in for me to easily know what part you are referring to.
Maybe include a few more photos and a description of what car you have and its type of headlight.
There are lots of aftermarket parts available for the S Type lights. Lots of headlight repair posts on this forum as well.

 

This is the headlight info for the right side. Its the middle headlight to the left if your looking at the car. Its a plastic piece that hold the headlight in place its. Broken off is all. I just need a part name. I cant seem to find it anywhere.
