International 9370 front and rear side marker bulbs both utilize a 67 bulb size. The replacement chart covers vehicle production spanning 1985 to 1987.
The year-by-year compatibility chart below provides a quick reference to verify the correct bulb size for your vehicle.
The International 9370 uses the type 67 bulb for both front and rear side marker positions across the 1985-1987 model years.
The type 67 is an ANSI-standard bulb recognized in both the United States and Canada, operating at 12 volts and 8 watts.
It is a single-filament bulb, meaning it serves only one lighting function rather than combining two, such as running and braking signals.
The type 67 uses a BA15s bayonet base, which is a single-contact bayonet mount with a 15mm collar width.
The type 67 is a lower-wattage variant of the 1156 bulb, which shares the same BA15s base type but draws significantly more power at approximately 26.9 watts.
Because the 1156 and type 67 share the same base, physical fitment is possible between the two, but the wattage difference means they are not electrically interchangeable without consideration of the socket and circuit ratings.
