I have searched the internet & parts stores in my attempt to locate an internal rear dome light which resides in my 2004 XJ8 within the ceiling beside the rear doors. I have obviously used the Hella name and tried three different numbers I found on the part assuming one of them should be the part number. I have not had any luck in locating this lamp to replace the existing one. The existing one works; but, it is loose within its holding on account of my son breaking the piece on the end of it (by his pushing-in too hard on it) which secures it in place. Anyone know where to purchase one of these? Thanks for any assistance.
