The year-by-year compatibility chart below provides a quick reference to verify the correct bulb size for your vehicle.
The Mitsubishi Fuso FM-HR uses the type 89 bulb for both front and rear side marker positions across the 1996-1998 model years.
The type 89 is an ANSI-standardized bulb recognized in both the United States and Canada, operating at 12 volts and 13 watts.
It is a single-filament bulb, meaning it serves one lighting function rather than combining two, such as running and braking, into a single unit.
The type 89 uses a BA15s bayonet base, a single-contact mount where the bulb locks into its socket with a twist rather than a threaded or plug-in connection.
The type 89 is a lower-wattage variant of the more common 1156 bulb, which shares the same BA15s bayonet base but draws higher wattage. This relationship is relevant to interchangeability, as the shared base type does not make the two bulbs direct replacements for each other in all applications.
