Land Rover Freelander front fog light bulbs use H11 size, while rear fog light bulbs use P21W or P21/5W size. The replacement chart covers 2002 to 2005 model years with corresponding bulb size specifications.
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 H11 bulb for the front fog light across the 2002-2005 model years. The H11 is a single-filament halogen bulb operating at 12V and 55W, built to the ECE standard recognized in Europe, worldwide markets, and the United States. Its base type is PGJ19-2.
The rear fog light of the Land Rover Freelander alternates between two bulb types depending on the model year and, in one case, the chassis number. The P21W and P21/5W are both ECE-standard signalling bulbs rated at 12V, but they differ in filament count and wattage output.
The P21W is a single-filament bulb rated at 21W and uses a BA15s bayonet base. It is fitted to the rear fog light on the 2002 and 2003 Freelander, as well as the 2005 model year.
The P21/5W is a dual-filament bulb with a BAY15d bayonet base, rated at 21W on its primary filament and 5W on its secondary filament. It is specified for the rear fog light on the 2002 Freelander and on 2004 models from chassis number 4A000001 onward.
The BA15s base of the P21W and the BAY15d base of the P21/5W are physically distinct. The BAY15d base features offset pins to prevent incorrect installation, while the BA15s base has a single contact and symmetrical pins. These two bulbs are not interchangeable despite their similar appearance.
For the 2004 Freelander rear fog light, the applicable bulb type is determined by the chassis number. Units from chassis 4A000001 onward take the P21/5W, while earlier 2004 production units are not covered by the listed specifications.
The H11 bulb's PGJ19-2 base is specific to the H11 type and is not shared with other common halogen bulbs such as the H9 or H8, which use visually similar but dimensionally distinct bases. Substituting those types into an H11 socket is not supported by the specifications.
All bulb types listed across both fog light positions operate on a 12V electrical system, consistent with standard automotive voltage.
