Additional Notes

The P21W is the fog light bulb used across all listed model years of the Jaguar F-Type, spanning 2014-2017 and 2021-2024.
The P21W is governed by ECE (Economic Commission for Europe) standards, which means it meets regulatory requirements across European and many worldwide markets.
As a single-filament bulb, the P21W is designed for one dedicated lighting function rather than serving dual roles such as combined stop and tail operation.
The P21W operates at 12 volts and consumes 21 watts, placing it in the standard low-voltage automotive electrical range common to most passenger vehicles.
The BA15s bayonet base is a single-contact fitting, distinguished from the dual-contact BA15d base. Substituting a dual-contact variant would result in an incorrect fitment for these fog light positions.
The "s" in BA15s denotes a single offset pin on the base, which physically prevents installation of incompatible bayonet bulbs with differing pin configurations.
