International 4400LP headlight bulbs use 9007 size for both high and low beam applications. The replacement chart covers 2011 to 2016 model years with corresponding bulb size specifications.
The year-by-year compatibility chart below provides a quick reference to verify the correct bulb size for your vehicle.
The 9007 bulb is the sole headlight bulb type specified for the International 4400LP across the 2011-2016 model years.
The 9007 is a dual-filament halogen bulb, meaning a single bulb unit contains two separate filaments to serve both high beam and low beam functions within one housing.
Because the 9007 handles both beam functions, the International 4400LP uses the same bulb size for its high beam and low beam headlight positions.
The 9007 operates on a 12-volt electrical system and carries wattage ratings of 65W for the high beam filament and 55W for the low beam filament.
The 9007 uses a PX29t base, which is a specific connector and mounting configuration; bulbs with a different base type are not physically interchangeable with this fitment even if their wattage or voltage ratings are similar.
The 9007 conforms to ANSI standards recognized in the United States and Canada, classifying it as a regulated bulb type with defined performance and construction requirements.
