International 4900 front side marker bulbs utilize 67 and 1895 bulb sizes, while rear side marker bulbs use 67 size specifications. The replacement chart covers vehicle production spanning 1992 to 1997 with corresponding bulb size data.
The year-by-year compatibility chart below provides a quick reference to verify the correct bulb size for your vehicle.
The International 4900 front side marker position uses two distinct bulb types across the 1992-1997 model years, with the 1895 fitted in 1992-1993 and 1995-1996, and the 67 fitted in 1994 and 1997.
The rear side marker position on the International 4900 uses the 67 bulb uniformly across all listed model years from 1992-1997.
The 67 bulb is a single-filament type with a BA15s bayonet base, rated at 12V and 8W, and is classified as a lower wattage variant of the 1156 bulb within the ANSI standard system used in the US and Canada.
The 1895 bulb is a miniature wedge type in a T5 form factor, rated at 12V and 0.9W under the same ANSI standard, representing a substantially lower power draw than the 67.
The BA15s bayonet base of the 67 bulb is a single-contact fitting, which is not interchangeable with wedge-base bulbs such as the 1895 without a socket adapter or housing modification.
Because the front side marker position on the International 4900 alternates between the 67 and the 1895 depending on the model year, the two bulb types serve the same position but are not interchangeable with each other due to differing base types and wattage ratings.
The wattage difference between the 67 (8W) and the 1895 (0.9W) is significant, with the 1895 drawing roughly one-ninth the power of the 67, which reflects a difference in intended socket and housing design rather than a simple substitution.
