Additional Notes

The Suzuki Equator uses the 921 bulb size across all four model years covered in the specifications, spanning 2009-2012.
The 921 bulb is a wedge-type unit, classified under the T15 designation, which refers to its tubular glass envelope size expressed in eighths of an inch.
Wedge bulbs do not use a separate metal base or pins. Instead, the glass envelope itself tapers at the bottom to form a friction fit within the socket, eliminating the need for a traditional bayonet or screw base.
The 921 operates at 12 volts and 16 watts, which is consistent with standard automotive electrical systems.
The 921 bulb conforms to ANSI standards and is recognized in both the United States and Canada, indicating a standardized specification shared across North American markets.
Because the 921 designation is an ANSI-standardized type, bulbs from different manufacturers carrying the same number are generally interchangeable, provided they match the 12V and 16W ratings.
