I have a question bout the 01 passat hella projector headlights, when doing an ebay search for them some of them come up as the headlight and corner light as one piece, and some have the square looking ones that u would also need a seperate corner light. The passat im buying has the 2 light setup out of the factory. Can i use ethier one or do i need the 2 seperates? did vw change the light setup mid-year or something?
