Additional Notes

The Nissan NV3500 uses the 921 bulb for the back up light across all available model years in these specifications, spanning 2012-2020.
The 921 is an ANSI-standardized bulb type, meaning its physical and electrical characteristics follow a defined North American standard recognized in both the United States and Canada.
The 921 bulb uses a wedge-style base, designated T15, which refers to a tubular bulb body approximately 15/8 of an inch wide that is held in its socket by friction rather than by pins or a bayonet mechanism.
The bulb operates at 12 volts, consistent with the standard electrical system voltage found in conventional passenger and commercial vehicles.
At 16 watts, the 921 falls within the low-wattage range typical of reverse lighting applications, where output requirements are moderate compared to headlighting functions.
The T15 wedge base format is shared by several bulb numbers in the same family, so substitution with a visually similar bulb of a different number may result in a wattage or voltage mismatch even if the base physically fits the socket.
