Additional Notes

The 1156 is the sole bulb type listed for the Nissan 310 back up light across all specified model years, covering 1979-1980 and 1982.
The 1156 is an ANSI-standardized bulb recognized in both the United States and Canada, meaning it conforms to a defined set of electrical and physical standards shared across those markets.
It operates on a 12-volt system at 21 watts, which is typical of standard incandescent automotive reverse lighting applications.
The 1156 uses a BA15s bayonet base, a single-contact fitting where the "s" denotes a single pin, as opposed to the dual-pin BA15d variant. This distinction is critical when sourcing a replacement, as the two base types are not interchangeable despite their similar appearance.
The 1156 is a single-filament bulb, meaning it serves one lighting function only. This differentiates it from dual-filament bulbs such as the 1157, which are used in applications requiring two brightness levels from a single housing.
