Additional Notes

The 921 bulb is the sole back up light bulb size listed across all model years of the Hyundai Veloster covered in these specifications.
The 921 is an ANSI-standardized bulb type, meaning its physical and electrical characteristics conform to a defined North American standard recognized in both the United States and Canada.
It uses a wedge-style base, designated T15, which refers to a tubular bulb body approximately 15 eighths of an inch wide. Wedge bases have no separate metal pins; the glass envelope itself is pinched at the bottom to form the electrical contact.
The 921 operates at 12 volts and draws 16 watts, figures consistent with standard automotive electrical systems.
The 2019 Hyundai Veloster carries a production date qualifier, specifying the 921 bulb for vehicles built from March 16, 2018 onward. This indicates a mid-cycle production change occurred for that model year, and fitment should be confirmed against the vehicle's build date before installation.
The specifications cover model years 2012-2017 and 2021 without production date qualifiers, meaning the 921 applies to all units within those years without restriction.
Because the 921 is an ANSI-standardized wedge bulb, it is generally interchangeable with other bulbs sharing the same T15 wedge base, 12V rating, and compatible wattage, provided the replacement meets the socket's physical and electrical requirements.
