Additional Notes

The Land Rover Freelander uses the P21W bulb for the back up light across the 2002-2005 model years.
The P21W is an ECE-regulated bulb type, meaning it conforms to European and international standards rather than SAE standards used in North American automotive lighting.
P21W operates at 12 volts with a 21-watt output, which is a typical rating for single-filament signalling applications such as reverse lights.
The P21W uses a BA15s bayonet base, where "BA" denotes a bayonet cap fitting, "15" refers to the 15mm base width, and the lowercase "s" indicates a single contact at the base.
Because the P21W is single-filament, it serves one lighting function only, distinguishing it from dual-filament variants such as the P21/5W, which would not be a correct substitute for this application.
The BA15s base is not interchangeable with the BA15d base, which carries two contacts. Substituting a BA15d bulb in a BA15s socket is not mechanically or electrically compatible.
