International L130 vehicles utilized 194 bulb size for front side marker applications and 97 bulb size for rear side marker positions. The replacement chart covers 1950 to 1952 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 L130 uses two distinct bulb types across its side marker positions for the 1950-1952 model years: the 194 at the front and the 97 at the rear.
The 194 is an ANSI-standardized miniature wedge bulb classified under the T10 form factor, operating at 12 volts and drawing 3.78 watts.
The T10 wedge base on the 194 requires no locking mechanism for retention, as the wedge shape itself holds the bulb within the socket.
The 97 is an ANSI-standardized single-filament bulb fitted with a BA15s bayonet base, operating at 12 volts and drawing 13 watts.
The BA15s designation on the 97 indicates a single-contact bayonet base with a 15mm collar, which is not interchangeable with BA15d double-contact variants.
The 97 is noted as a variant of the 1156, though the two are not identical and substitution between them warrants verification of wattage and base pin alignment before use.
The 97 draws 13 watts compared to the 194's 3.78 watts, reflecting the functional difference between a rear marker application and a lower-intensity front position lamp.
Both the 194 and 97 conform to ANSI standards recognized in the United States and Canada, placing them within a shared North American standardization framework.
