International 7100 front and rear side marker bulbs utilize 67 and 1895 bulb sizes for the front position, with the rear side marker requiring a 67 size bulb. The replacement chart covers 1992 through 1995 vehicle 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 67 bulb is the dominant type across the side marker specifications for the International 7100, appearing in both front and rear positions across 1992-1995, with the sole exception of the 1994 front side marker.
The 67 bulb follows the ANSI standard recognized in both the US and Canada, operates at 12V and 8W, and uses a BA15s single-contact bayonet base with a single filament.
As a single-filament bulb, the 67 serves only one lighting function per socket, which is consistent with its use in side marker applications rather than combined stop or turn functions.
The 67 is a lower-wattage variant of the 1156 bulb. Both share the BA15s bayonet base, though the difference in wattage means they are not interchangeable without accounting for the electrical load difference.
The 1994 front side marker position on the International 7100 calls for the 1895 bulb rather than the 67 used in all other positions and years listed.
The 1895 is a miniature wedge bulb of the T5 type, operating at 12V and 0.9W. Its wedge base design is physically incompatible with the BA15s bayonet socket required by the 67 bulb.
The significant wattage difference between the 1895 (0.9W) and the 67 (8W) means the two bulb types serve distinctly different electrical roles and cannot substitute for one another regardless of socket compatibility.
The rear side marker position uses the 67 bulb consistently across all four model years listed, 1992-1995, without variation.
