The Land Rover Freelander brake light requires a P21/5W bulb size for proper installation and function. Data for the bulb specifications covers the range from 2002 through 2005.
The year-by-year compatibility chart below provides a quick reference to verify the correct bulb size for your vehicle.
The Land Rover Freelander uses the P21/5W bulb for its brake lights across the 2002-2005 model years.
The P21/5W is a dual-filament bulb, with one filament rated at 21W for the brake and turn signal function and a second filament rated at 5W for the tail light function.
The P21/5W uses a BAY15d bayonet base, a two-pin offset base designed to prevent incorrect installation by ensuring the bulb can only be seated in one orientation.
The P21/5W operates on a 12V circuit and follows the ECE standard, which is the regulatory framework used across Europe and much of the wider world.
The center high mount stop light on the Freelander uses the 921 bulb across the same 2002-2005 model years.
The 921 is a single-filament wedge bulb of the T15 form factor, rated at 12V and 16W, and follows the ANSI standard used in the United States and Canada.
The T15 wedge base of the 921 bulb relies on spring tension from the socket contacts rather than a bayonet or screw mechanism to hold the bulb in place.
The P21/5W and the 921 are not interchangeable, as they differ in base type, filament count, wattage, and regulatory standard.
The dual-filament design of the P21/5W means a single housing serves two distinct lighting functions, which is a common arrangement in combined brake and tail light assemblies.
The use of an ANSI-standard bulb in the center high mount stop light alongside an ECE-standard bulb in the main brake lights reflects a mixed specification across the Freelander's lighting system for this generation.
