Additional Notes

The Kia Soul uses the 921 bulb size for the back up light across all model years from 2010 to 2024.
The 921 is a wedge-type bulb, classified under the T15 designation, which refers to its tubular shape measuring 15 eighths of an inch in width.
Wedge bulbs are named for their wedge-shaped base, which holds the bulb in place without a separate metal socket or pins, relying instead on tension from the housing.
The 921 operates at 12 volts and draws 16 watts, which are standard ratings for incandescent automotive reverse lighting applications.
The 921 conforms to ANSI standards as recognized in both the United States and Canada, meaning it meets a defined set of dimensional and electrical specifications shared across manufacturers.
Because the 921 is an ANSI-standardized bulb, it is interchangeable with any other bulb carrying the same 921 designation regardless of brand, provided the replacement also meets the T15 wedge form and 12V/16W ratings.
The consistent use of the 921 across all fifteen model years of the Kia Soul means a single bulb specification applies to the entire production run covered by these records.
