International R130 side marker bulbs utilize 194 size for front applications and 97 size for rear positions. The replacement chart covers 1953 to 1955 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 R130 uses two distinct bulb types across its side marker positions: the 194 at the front and the 97 at the rear, both conforming to ANSI standards recognized in the United States and Canada.
The 194 bulb is a T10 miniature wedge type, operating at 12 volts and drawing 3.78 watts, making it a low-wattage lamp suited for marker and clearance lighting applications.
The T10 wedge base of the 194 bulb requires no separate socket retainer, as the wedge-shaped base itself creates the electrical contact when inserted directly into a compatible housing.
The 97 bulb is a single-filament type mounted on a BA15s bayonet base, operating at 12 volts and drawing 13 watts, which is substantially higher than the front marker bulb.
The BA15s designation indicates a single-contact bayonet base with a 15mm collar, a base type that is not interchangeable with the wedge-style base of the 194 bulb.
The 97 bulb is described as a variant of the 1156, meaning it shares the same BA15s base configuration, though the two are not necessarily identical in wattage or filament design and should not be substituted without confirming the specific ratings.
For the International R130 across model years 1953-1955, the front side marker position consistently calls for the 194 bulb under the Light Duty classification.
The rear side marker position on the International R130 for 1953-1955 consistently requires the 97 bulb under the Light Duty classification, a higher-wattage lamp than its front counterpart.
Because the front and rear side marker positions use bulbs with different base types, a wedge base versus a bayonet base, the two are physically non-interchangeable regardless of voltage compatibility.
The Light Duty classification applied to all listed entries indicates these specifications pertain to a specific vehicle configuration, and fitment accuracy depends on confirming that the vehicle in question falls within that same duty rating.
