The International 4600LP uses a 1895 bulb size for front side marker applications and a 67 bulb size for rear side marker positions. The replacement chart covers 1992 to 1994 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 4600LP uses two distinct bulb types across its front and rear side marker positions for the 1992-1994 model years: the 1895 at the front and the 67 at the rear.
Both the 1895 and 67 bulbs conform to ANSI standards recognized in the United States and Canada.
The 1895 is a T5 miniature wedge bulb rated at 12V and 0.9W. The T5 designation refers to a tubular bulb with a 5/8-inch body width, and the wedge base means it is held in its socket by the glass envelope itself rather than a separate metal base.
The 67 is a single-filament bulb with a BA15s bayonet base, rated at 12V and 8W. The BA15s designation indicates a single-contact bayonet fitting with a 15mm base width.
The 67 bulb is described as a lower wattage variant of the 1156. While the 1156 is also a single-filament BA15s bulb, the two are not identical in output, and substituting one for the other may affect brightness and circuit load.
The wattage difference between the front and rear side marker bulbs is substantial. The rear 67 bulb draws 8W compared to the front 1895 at 0.9W, reflecting the greater visibility demands typically placed on rear marker lighting.
The wedge base of the 1895 is not physically compatible with the BA15s bayonet socket used by the 67, making the two bulbs non-interchangeable between front and rear positions.
