Mitsubishi Fuso FE-HD front and rear side marker bulbs use 89 size bulbs. The replacement chart covers 1996 to 1998 vehicle production years with 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-HD 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 with a 15mm collar and a single locating pin on the side.
As a single-filament bulb, the 89 serves one lighting function per socket, which is consistent with side marker applications that require only steady illumination.
The 89 is a lower wattage variant of the 1156 bulb. While both share the BA15s base type, the reduced wattage of the 89 means the two are not directly interchangeable without accounting for the difference in power draw and light output.
The shared bulb specification across both the front and rear side marker positions on the FE-HD means a single bulb type covers all four side marker sockets on the vehicle.
