Additional Notes

The Hyundai Azera uses the 921 bulb for the back up light position across all listed model years from 2006-2017, representing a consistent fitment throughout the entire production span covered by these specifications.
The 921 is a wedge-type bulb, classified under the T15 designation, which refers to its tubular glass envelope width of 15/8 of an inch. The wedge base replaces a traditional metal contact with a pinched glass base that makes direct electrical contact with the socket.
The 921 operates at 12 volts and draws 16 watts, placing it in the range typical for reverse lighting applications where adequate illumination behind the vehicle is required.
The 921 bulb conforms to ANSI standards as recognized in both the United States and Canada, meaning units sold in either market share the same bulb specification for the Azera back up light position.
The T15 wedge format of the 921 is physically distinct from bayonet and screw-base bulb types, and substitution with those base types is not compatible with the Azera's back up light socket design.
