Additional Notes

The 921 bulb is the sole back up light bulb size listed for the Hyundai Santa Fe Sport across all model years in the specifications, covering 2013-2018.
The 921 is a wedge-type bulb, designated T15, which refers to its tubular shape with a width of 15 units in the T-series sizing convention. The wedge base design means the bulb is held in place by the socket itself rather than by pins or a bayonet mechanism.
The 921 operates at 12 volts and draws 16 watts, which is standard for reverse lighting applications in passenger vehicles of this type.
The 921 designation follows ANSI standards recognized in both the United States and Canada, meaning the bulb conforms to a defined set of electrical and physical specifications shared across those markets.
Because the 921 is an ANSI-standardized wedge bulb, it is interchangeable with other bulbs that share the T15 wedge base and the same voltage and wattage ratings, provided the replacement meets those same electrical parameters.
