For the 2015 Ford Expedition, headlight bulb fitment depends on whether the vehicle has projector-type headlights. Models with projector-type headlights use 9005 for the low beam and H9 for the high beam. Models without projector-type headlights use H11 for the low beam and 9005 for the high beam. Confirm the headlight design before ordering.
