Additional Notes

The Nissan TITAN uses the 921 bulb size for its back up light across all specified model years from 2004 to 2024.
The 921 bulb is classified under the ANSI standard, which is the recognized specification system for automotive lighting in the United States and Canada.
This bulb follows the T15 wedge base design, meaning it is held in place by friction rather than a twist-lock or bayonet mechanism, and is removed by pulling it straight out of its socket.
The 921 operates at 12 volts and 16 watts, which are standard electrical values consistent with a vehicle's 12-volt DC electrical system.
The consistent use of the 921 across the 2004-2024 TITAN model years indicates a high degree of interchangeability for this position within the nameplate's production span.
The T15 wedge form factor is shared by several bulb numbers in the ANSI system, so substitutions should be confirmed against the 921 designation specifically, as wattage and voltage ratings differ between wedge bulb variants.
