The Mitsubishi Fuso FM-SR uses 89 bulb size for both front and rear side marker positions. The replacement chart covers 1996-1997 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 Mitsubishi Fuso FM-SR uses the 89 bulb for both front and rear side marker positions across the 1996-1997 model years.
The 89 is an ANSI-standardized bulb recognized across the United States and Canada, operating at 12 volts and 13 watts.
The 89 bulb uses a BA15s bayonet base, which is a single-contact base type with a 15mm collar and a single locating pin on the side.
As a single-filament bulb, the 89 serves functions that require only one lighting mode, making it appropriate for side marker applications.
The 89 bulb is a lower wattage variant of the 1156, meaning the two share the same BA15s base configuration but differ in power output, and they are not directly interchangeable despite their physical similarities.
