Additional Notes

The Nissan 280ZX uses the 1156 bulb for its back up light across all listed model years, spanning 1979-1983.
The 1156 is a single-filament bulb, meaning it serves only one electrical function, which in this application is the reverse light circuit.
It operates on a 12-volt system and draws 21 watts, consistent with standard automotive incandescent reverse lighting of that era.
The 1156 uses a BA15s bayonet base, where "BA15s" denotes a single-contact bayonet fitting with a 15mm base width.
The BA15s base has a single contact pin, which distinguishes it from the dual-pin BA15d base used on double-contact bulbs. These two base types are not interchangeable.
The 1156 designation follows ANSI standards applicable in the United States and Canada, confirming its use within North American market specifications.
