The Mitsubishi Fuso FE front and rear turn signal bulbs both utilize a 1156 size. 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 Mitsubishi Fuso FE uses the 1156 bulb for both its front and rear turn signals across the 1987-1998 model years.
The 1156 is a single-filament bulb, which is the appropriate construction for a dedicated turn signal application, as it does not need to serve a secondary function such as braking.
It operates at 12 volts and 21 watts, a wattage typical of incandescent turn signal bulbs in light and medium commercial vehicles of that era.
The 1156 uses a BA15s bayonet base, where "BA" denotes a bayonet cap fitting, "15" refers to the 15mm base width, and the lowercase "s" indicates a single contact at the base, consistent with its single-filament design.
The 1156 conforms to ANSI standards and is recognized in both the United States and Canada, placing it within a widely distributed North American bulb classification system.
Because the same bulb size applies to both the front and rear turn signal positions across all listed model years, a single bulb type services all four turn signal sockets on the vehicle.
The BA15s bayonet base of the 1156 is not interchangeable with the BA15d base found on dual-filament bulbs such as the 1157, as the single-contact and dual-contact bases differ in their pin and socket configurations.
