Additional Notes

The Nissan 200SX uses the 1156 bulb for its back up light across all listed model years, spanning 1977-1988 and 1995-1998.
The 1156 is an ANSI-standardized bulb, meaning its physical and electrical specifications are governed by a recognized North American standard used in both the United States and Canada.
The 1156 operates on a 12-volt electrical system and draws 21 watts, which is consistent with standard automotive reverse lighting requirements.
The 1156 is a single-filament bulb, 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-style 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 single-contact BA15s base of the 1156 is not interchangeable with the BA15d base found on dual-filament bulbs such as the 1157, despite the two types sharing a similar physical appearance and base width.
