Additional Notes

The 921 bulb is the sole tail light bulb type specified across all listed model years of the Hyundai Azera, covering the 2012-2017 range.
The 921 bulb follows the ANSI standard, which is the recognized specification body for lighting components in the United States and Canada.
It uses a wedge-style base, designated T15, which refers to a tubular glass envelope approximately 15 eighths of an inch wide fitted with a pinched, solderless wedge base rather than a bayonet or screw fitting.
The bulb operates at 12 volts and draws 16 watts, consistent with standard automotive low-voltage electrical systems.
The 2012 Hyundai Azera specification carries a production start qualifier of from 12/14/2011, meaning vehicles assembled before that date fall outside this fitment.
The 2017 Azera specification carries a production cutoff of to 12/8/2016, meaning vehicles assembled after that date fall outside this fitment.
The wedge base design of the T15 format is not interchangeable with bayonet-base or screw-base bulb formats, even when wattage or voltage ratings are otherwise similar.
