International 4600 Headlight Bulb Size

International 4600 high beam and low beam headlight bulbs both use the H6054 size. The replacement chart covers vehicle production from 1992 to 1995.

The year-by-year compatibility chart below provides a quick reference to verify the correct bulb size for your vehicle.

Description	Bulb Size
ANSI standard (US & Canada). 5x7-inch rectangular sealed beam unit. Not a replaceable bulb — the entire unit is replaced. 12V.	H6054

The International 4600 uses the H6054 bulb size across both high beam and low beam headlight positions for the 1992-1995 model years.
The H6054 is an ANSI-standardized sealed beam unit recognized in both the United States and Canada, operating at 12 volts.
Sealed beam units such as the H6054 house the filament, reflector, and lens within a single fused glass assembly, meaning the entire unit requires replacement rather than an internal bulb.
The H6054 follows a 5x7-inch rectangular form factor, a standardized size that allows interchangeability across various vehicles using the same ANSI designation.
Because the International 4600 uses the same H6054 unit for both high and low beam functions, the two positions accept the same replacement part, which is a characteristic of certain sealed beam configurations where a single unit serves dual beam roles.
