The International 4600LP headlight bulb uses an H6054 size for both high beam and low beam functions. The replacement chart covers 1992 to 1994 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 the sole bulb type listed across all headlight positions in the International 4600LP specifications, covering both high beam and low beam functions for the 1992-1994 model years.
The H6054 is a 5x7-inch rectangular sealed beam unit operating at 12 volts, conforming to ANSI standards recognized in both the United States and Canada.
As a sealed beam unit, the H6054 is not a replaceable bulb in the conventional sense. When the light fails, the entire sealed unit requires replacement rather than an internal filament or capsule.
The H6054 designation serves a dual-function role in the International 4600LP, with the same unit specified for both the high beam and low beam headlight positions across all listed years.
The ANSI standardization of the H6054 means the unit conforms to fixed dimensional and electrical specifications, which historically allows for interchangeability between compliant units from different manufacturers.
Because the H6054 is a standardized sealed beam format, fitment is governed by the physical housing size and connector type rather than by brand, provided the replacement unit meets the same ANSI specification.
