Mitsubishi Fuso FE front and rear side marker bulbs utilize a 89 size bulb specification. The replacement chart covers vehicle production spanning 1987 to 1998.
The year-by-year compatibility chart below provides a quick reference to verify the correct bulb size for your vehicle.
The 89 bulb is the sole bulb type specified for the Mitsubishi Fuso FE across all listed side marker positions and model years.
The 89 bulb follows the ANSI standard recognized in both the United States and Canada, placing it within a widely adopted North American automotive lighting classification system.
It is a single-filament bulb, meaning it serves one lighting function per socket rather than switching between two intensity levels as a dual-filament bulb would.
The 89 bulb uses a BA15s bayonet base, a single-contact bayonet mount that locks into its socket with a twist, without a screw thread.
Its electrical rating is 12 volts and 13 watts, consistent with standard 12V automotive electrical systems.
The 89 is a lower-wattage variant of the 1156 bulb. Both share the BA15s bayonet base, but the 1156 operates at a higher wattage, making the two types electrically non-equivalent despite their physical similarity.
Because the 89 and 1156 share the same base type, a 1156 bulb can physically seat in a socket designed for an 89, but the wattage difference means substituting one for the other falls outside the stated specification.
The front side marker positions on the Mitsubishi Fuso FE use the 89 bulb across the full 1987-1998 model year range covered in the specifications.
The rear side marker positions carry the same 89 bulb specification across the identical 1987-1998 range, making the front and rear side marker sockets interchangeable in terms of bulb type.
