International A130 vehicles utilized 194 bulb size for front side marker applications and 97 bulb size for rear side marker positions. The replacement chart covers 1957 to 1958 model 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 A130 uses the 194 bulb for the front side marker position across the 1957-1958 model years, in Light Duty configurations.
The 194 is a T10 miniature wedge bulb rated at 12V and 3.78W, conforming to ANSI standards recognized in both the United States and Canada.
The T10 wedge base on the 194 requires no locking mechanism, as the wedge-shaped base itself holds the bulb in place within the socket.
The rear side marker position on the 1957-1958 International A130 (Light Duty) calls for the 97 bulb, a notably higher-wattage unit than its front counterpart.
The 97 bulb operates at 12V and 13W, making it significantly more powerful than the 3.78W front side marker bulb used on the same vehicle.
The 97 uses a BA15s single-contact bayonet base, which is a single-filament configuration with a 15mm bayonet collar and one contact pin offset to one side.
The 97 is classified as a variant of the 1156 bulb family, though the two are not necessarily interchangeable due to differences in wattage and base pin positioning between specific variants.
Both the 194 and 97 conform to ANSI standards, meaning their physical and electrical characteristics follow a defined specification applicable across the United States and Canada.
