Additional Notes

The 1156 is the specified back up light bulb size for the Nissan Pickup across the 1995-1997 model years.
The 1156 is an ANSI-standardized bulb type, meaning its physical and electrical characteristics conform to a defined North American specification 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 applications.
The 1156 is a single-filament bulb, meaning it serves one lighting function only, as opposed to dual-filament types that handle two functions such as braking and running light duties simultaneously.
The 1156 uses a BA15s bayonet base, a single-contact mount where the bulb is inserted and rotated to lock into the socket, distinguishing it from screw-base or wedge-base alternatives that are not interchangeable with this fitment.
