International B102 vehicles utilized 194 bulb size for front side marker applications and 97 bulb size for rear side marker positions. The replacement chart documents bulb specifications across the 1959-1960 production period.
The year-by-year compatibility chart below provides a quick reference to verify the correct bulb size for your vehicle.
The International B102 uses two distinct bulb types across its front and rear side marker positions for the 1959-1960 model years, with Light Duty trim variants specified for both.
The 194 bulb serves as the front side marker across both model years. It follows the ANSI standard recognized in the US and Canada and is a T10 miniature wedge type operating at 12V and 3.78W.
The T10 wedge form factor of the 194 bulb means it uses a friction-fit base rather than a bayonet or screw mount, which is a relevant consideration when sourcing a replacement.
The rear side marker position on the B102 for 1959-1960 uses the 97 bulb, a single-filament type with a BA15s bayonet base operating at 12V and 13W.
The 97 bulb draws significantly more wattage than the 194, reflecting the different luminous output demands placed on rear versus front side marker positions.
The 97 bulb is noted as a variant of the 1156. While the two share a BA15s bayonet base, they are not identical, and substituting one for the other without confirming wattage and voltage compatibility may result in incorrect fitment.
Both the 194 and 97 bulbs conform to ANSI standards applicable in the US and Canada, indicating standardized electrical and physical specifications within those markets.
The BA15s base designation on the 97 bulb refers to a single-contact bayonet cap with a 15mm collar, distinguishing it from dual-contact bayonet bases used in other automotive applications.
