Additional Notes

The 921 bulb follows the ANSI standard used in the United States and Canada, while the P21W follows the ECE standard adopted across Europe and much of the world.
The Kia Stinger uses the 921 bulb for its back up light across the 2018-2020 and 2022 model years.
The 921 is a T15 wedge-base bulb rated at 12V and 16W, meaning it draws less wattage than the P21W.
The 2023 Kia Stinger specifies the P21W for its back up light, which differs from the bulb type used in prior model years.
The P21W operates at 12V and 21W, making it a higher-wattage single-filament bulb compared to the 921.
The P21W uses a BA15s bayonet base, which is a single-contact bayonet fitting, and is physically and electrically incompatible with the wedge socket used by the 921.
Because the 2023 model specifies a P21W with a bayonet base while earlier model years specify a 921 wedge bulb, the two bulb types are not interchangeable across those model years.
