International B130 side marker bulbs utilize 194 size for front applications and 97 size for rear positions. The replacement chart covers 1959 to 1960 production years with corresponding bulb specifications.
The year-by-year compatibility chart below provides a quick reference to verify the correct bulb size for your vehicle.
The International B130 uses two distinct bulb types across its front and rear side marker positions for the 1959-1960 model years, with Light Duty trim applications covered by both.
The 194 bulb serves as the front side marker across both model years. It is an ANSI-standardized miniature wedge type in a T10 form factor, rated at 12 volts and 3.78 watts.
The T10 wedge base of the 194 bulb connects without a separate metal base, relying instead on the wedge-shaped glass envelope to make contact within the socket.
The 97 bulb is specified for the rear side marker position across the same 1959-1960 model years. It uses a BA15s single-contact bayonet base and is rated at 12 volts and 13 watts.
The 97 bulb is described as a variant of the 1156. While the two share a BA15s bayonet base, they differ in wattage, and the 97 draws significantly less power than the 1156, which is rated at approximately 26.9 watts.
The wattage difference between the front and rear side marker bulbs is substantial. The rear 97 bulb at 13 watts draws more than three times the power of the front 194 bulb at 3.78 watts, reflecting the differing visibility requirements of each position.
Both the 194 and 97 bulbs conform to ANSI standards recognized in both the United States and Canada, indicating standardized electrical and physical specifications across North American markets.
The BA15s designation on the 97 bulb denotes a single-contact bayonet base with a 15mm collar, distinguishing it from dual-contact bayonet bases used in other automotive applications. Substituting a dual-contact base bulb into a BA15s socket is not compatible.
