Mitsubishi Fuso FE-SP front and rear side marker bulbs use 89 size bulbs for illumination. The replacement chart covers 1996 to 1998 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 FE-SP uses the 89 bulb for both front and rear side marker positions across the 1996-1998 model years.
The 89 is an ANSI-standardized bulb type 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 identified by a 15mm collar and a single locating pin on its side.
As a single-filament bulb, the 89 serves one lighting function per socket, which is consistent with its use in side marker applications.
The 89 is a lower wattage variant of the 1156 bulb, sharing the same BA15s bayonet base but drawing less power at 13W compared to the 1156's 26.9W rating.
Because the 89 and 1156 share the same base type, physical fitment of a 1156 into an 89 socket is possible, though the higher wattage of the 1156 may exceed the electrical tolerances of the socket or circuit.
