Additional Notes

The Mitsubishi Fuso FE uses the 1156 bulb for its back up light across all listed model years from 1987-1998.
The 1156 is an ANSI-standardized bulb type, meaning its physical and electrical specifications are governed by a recognized North American standard used in the United States and Canada.
The 1156 operates on a 12-volt electrical system and draws 21 watts, which is typical for incandescent reverse lighting applications.
The bulb is a single-filament type, meaning it serves one lighting function only, as opposed to dual-filament bulbs that handle two functions such as braking and running light from a single unit.
The 1156 uses a BA15s bayonet base, where "BA15s" denotes a bayonet mount with a 15mm base width and a single contact pin, which locks the bulb into the socket with a push-and-twist motion.
The BA15s single-contact base of the 1156 is not interchangeable with the BA15d base found on dual-filament bulbs such as the 1157, despite the similar bayonet mount style, as the pin configuration differs.
