After the metal headlight bulbholder and spring clip assembly as shown in the picture.

It's for the passenger side on mine, although not sure if the part would be the same on both lights.

 

Can you not buy them as a single part. I do have one somewhere.

 

Not sure, think you have to buy the whole assembly.

If you could see if you have one lying around, that would be great.

 

I did have a pair of damaged ones knocking about, will have a look for you, are they sided? ...as in do you need O/S or N/s or will either do.

(Dont get your hopes up as they may have been included in last years tip run.)
