Additional Notes

The P21W is the sole back up light bulb type specified for the Mini Cooper Clubman across the 2016-2023 model years.
The P21W is defined under ECE (Economic Commission for Europe) standards, a regulatory framework used across Europe and numerous other markets worldwide.
As a single-filament bulb, the P21W is dedicated to one lighting function, which in this application is the back up light.
The P21W operates at 12 volts and consumes 21 watts, figures typical of standard incandescent automotive signalling bulbs.
The P21W uses a BA15s bayonet base, a single-contact fitting where the "s" denotes a single pin offset to one side of the base.
The BA15s base is not interchangeable with the BA15d base, which carries two contact pins; substituting one for the other is not possible without a socket mismatch.
