Do not touch the bulb with your bare hands when inserting into socket.Oil from your hands can shorten the life of the bulb.Hold bulb with tissue paper when installing.

This might be a problem the carmaker knows about. Ask the dealer if there have been any TSBs (technical service bulletins) or other advice from Ford about it.
