ok so i found many new projector fog lights for a jetta? and a golf? i kno the golf is the same well almost? whats the difference in size? for the fogs for the golf/jetta? and the rabbit? cuz i have an 07 rabbit and i want my fogs already but not really sure on which ones to get? if i get projectors will it be easier to install hid's? as compared to regular/reflector fogs?
