Additional Notes

The P21W is the sole back up light bulb type specified for the Land Rover Range Rover Sport across the 2006-2013 model years.
The P21W is an ECE-standard single-filament bulb, meaning it carries one filament dedicated to a single lighting function rather than serving dual purposes such as combined stop and tail operation.
The P21W operates at 12 volts and 21 watts, which places it within the standard low-voltage electrical architecture common to passenger vehicles of this era.
The bulb uses a BA15s bayonet base, a single-contact fitting where the "s" denotes a single pin, as opposed to the dual-contact BA15d variant. These two base types are not interchangeable despite sharing the same 15mm collar width.
The ECE designation indicates the P21W conforms to United Nations Economic Commission for Europe regulations, a standard widely adopted outside North America. North American SAE-equivalent bulbs with similar wattage ratings may differ in base configuration or photometric output and are not confirmed substitutes per these specifications.
