Additional Notes

The Nissan 710 uses the 1156 bulb for the back up light across the 1974-1977 model years.
The 1156 is an ANSI-standardized bulb, meaning its physical and electrical specifications are governed by a recognized North American standard shared across the United States and Canada.
The 1156 is a single-filament bulb, which means it serves one lighting function only, as opposed to dual-filament bulbs that handle two functions such as braking and running light simultaneously.
The bulb operates at 12 volts and 21 watts, consistent with standard 12V automotive electrical systems found in passenger vehicles of that era.
The 1156 uses a BA15s bayonet base, where "BA15s" denotes a bayonet cap with a 15mm base width and a single contact pin, which locks the bulb into its socket with a push-and-twist motion.
The BA15s single-contact base is not interchangeable with the BA15d base, which carries two contact pins and is used on dual-filament bulbs such as the 1157. Substituting one for the other is not possible without a socket modification.
