International C130 utilizes a 194 bulb size for front side marker and 97 bulb size for rear side marker applications. The replacement chart covers 1961 to 1962 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 International C130 uses two distinct bulb types across its front and rear side marker positions for the 1961-1962 model years: the 194 at the front and the 97 at the rear.
Both the 194 and 97 are ANSI-standardized bulbs recognized in the United States and Canada, operating on a 12-volt electrical system.
The 194 is a T10 miniature wedge bulb, meaning it uses a wedge-style base rather than a metal socket pin, and draws 3.78 watts, placing it in the low-wattage range typical of marker and courtesy lighting.
The 97 is a single-filament bulb with a BA15s bayonet base, a single-contact bayonet mount that locks into its socket with a twist. At 13 watts, it draws considerably more power than the 194.
The 97 is classified as a variant of the 1156 bulb family. Despite this relationship, the two are not identical, and substitution between them warrants verification of base compatibility and wattage tolerance before use.
The front and rear side marker positions on the International C130 (1961-1962) are not interchangeable with each other, as they require different bulb types with different base designs and wattage ratings.
The Light Duty designation present across all listed entries applies to both model years and both marker positions, indicating these specifications correspond to the light-duty variant of the C130.
