I've just noticed that my right corner light is loose. (After I got it back from the bodyshop a month ago. The ball-socket joint part is missing leaving only the ball which is attached to the light. Where can I get the missing piece or pieces without shelling out for the entire headlight housing??

 

are you referring to the piece of plastic that the ball pops into?
you should be able to get one from the dealer

 

or you could try the cheaper route and go to a junkyard.

 

Thanks peeps ! I'll try the dealer. Hopefully I won't have to shell out $5 for a piece of plastic !
