Additional Notes

The Hyundai Venue uses two distinct bulb types across its model years for the back up light position: the P21W for the 2024 model year and the 921 for the 2020-2023 model years.
The 921 bulb follows the ANSI standard used in the US and Canada. It is a T15 wedge-type bulb rated at 12V and 16W.
The P21W bulb follows the ECE standard used in Europe and worldwide. It is a single-filament signalling bulb with a BA15s bayonet base rated at 12V and 21W.
The BA15s bayonet base of the P21W is a twist-and-lock style fitting, which is physically incompatible with the wedge-style socket that accepts the 921 bulb. The two types are not interchangeable.
The 921 wedge bulb draws 16W, while the P21W draws 21W. Installing a higher-wattage bulb in a socket rated for a lower-wattage type can stress the socket and wiring.
The shift from the 921 to the P21W in the 2024 Hyundai Venue reflects a change in the base fitting type, meaning a direct substitution between model years is not possible without a corresponding socket change.
