Additional Notes

The Mitsubishi Fuso FM-MR 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 design that seats and locks with a twist motion.
As a single-filament bulb, the 89 serves one lighting function per socket, which is consistent with the side marker role of indicating vehicle presence rather than signaling or braking.
The 89 is a lower wattage variant of the 1156 bulb. While both share the BA15s base, the reduced wattage of the 89 means the two types are not directly interchangeable without accounting for the difference in power draw.
