The Mitsubishi Fuso FM-MR front and rear turn signal bulbs both use a 1156 size. The replacement chart covers vehicle production years spanning 1996 to 1998.
The year-by-year compatibility chart below provides a quick reference to verify the correct bulb size for your vehicle.
The Mitsubishi Fuso FM-MR uses the 1156 bulb for both its front and rear turn signals across the 1996-1998 model years.
The 1156 is a single-filament bulb, meaning it is dedicated to one lighting function rather than serving dual purposes such as combined stop and turn signal operation.
It operates on a 12-volt electrical system and draws 21 watts, which is typical for incandescent automotive turn signal applications.
The 1156 uses a BA15s bayonet base, a single-contact fitting where the bulb is inserted and rotated to lock into place.
The BA15s base is not interchangeable with the BA15d base, which is a dual-contact bayonet fitting used on two-filament bulbs such as the 1157. Substituting one for the other is not possible without a socket modification.
The 1156 designation follows ANSI standards recognized in both the United States and Canada, indicating a standardized specification for base type, voltage, wattage, and light output.
Because the same bulb type is specified for both the front and rear turn signal positions, a single replacement part covers all four turn signal sockets on the vehicle.
