The International 5900i uses H6054 bulb size for both high beam and low beam headlight applications. The replacement chart covers 2011 to 2012 vehicle production 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 H6054 is an ANSI-standard sealed beam unit used in both the high beam and low beam positions of the International 5900i for the 2011-2012 model years.
The H6054 follows a 5x7-inch rectangular sealed beam format, meaning the lens, reflector, and filament are fused into a single glass housing rather than a separate bulb within a housing.
Because the H6054 is a sealed beam unit, the entire assembly requires replacement when the light fails, as the filament is not accessible or serviceable independently.
The H6054 operates at 12 volts and conforms to ANSI standards recognized in both the United States and Canada.
The shared H6054 specification across both the high beam and low beam positions indicates that a single sealed beam unit type serves both lighting functions on this vehicle.
