Additional Notes

The 921 bulb is the dome light bulb size for the Dodge Sprinter across the 2005-2006 model years.
The 921 bulb follows the ANSI standard, which is the recognized specification system used in the United States and Canada for automotive lighting components.
The 921 is a wedge-type bulb, meaning it uses a wedge-shaped plastic base that friction-fits directly into a socket without requiring a separate metal connector or bayonet pins.
The T15 designation refers to the bulb's tubular shape, with the numeric portion indicating a width of 15 eighths of an inch across the widest point of the glass envelope.
The 921 operates at 12 volts, consistent with the standard electrical system voltage found in passenger and commercial vehicles.
At 16 watts, the 921 produces a moderate output level typical of interior dome lighting applications.
