Additional Notes

The 921 bulb is the specified back up light bulb size across all listed model years of the Hyundai Genesis, spanning 2009-2016.
The 921 is a wedge-type bulb, classified under the T15 designation, which refers to its tubular glass envelope size measured in eighths of an inch.
Operating at 12 volts and 16 watts, the 921 falls within the standard low-wattage range typical of reverse lighting applications in passenger vehicles.
The 921 bulb carries ANSI standardization recognized in both the United States and Canada, meaning it conforms to a defined set of electrical and physical specifications shared across manufacturers.
For the 2015 Hyundai Genesis, the 921 bulb size applies specifically to vehicles equipped with Halogen Capsule Headlamps, indicating a trim or package-level fitment condition for that year.
The wedge base design of the 921 requires no separate metal base or bayonet pins, as the glass envelope itself acts as the retention mechanism within the socket.
