Additional Notes

The Mitsubishi Fuso FK uses the ANSI 89 bulb for its license plate position across all listed model years from 1986-1998.
The 89 bulb operates on a 12-volt electrical system and draws 13 watts, placing it in the low-wattage range for automotive incandescent lighting.
As a single-filament bulb, the 89 is designed exclusively for non-switching applications such as license plate illumination, where only one constant light output level is required.
The 89 uses a BA15s bayonet base, a single-contact fitting where the bulb is inserted and rotated to lock into the socket.
The 89 is a lower-wattage variant of the 1156 bulb. While both share the BA15s bayonet base, the wattage difference means the two are not interchangeable without accounting for the electrical load difference.
