The Land Rover Range Rover Sport fog light requires bulb size H7 or P21W depending on the specific version. Data for the bulb sizes covers the range from 2006 to 2009.
The year-by-year compatibility chart below provides a quick reference to verify the correct bulb size for your vehicle.
The H11 is the most widely specified front fog light bulb across the Land Rover Range Rover Sport lineup, appearing in model years 2007-2019. It is a single-filament halogen bulb rated at 12V and 55W, fitted with a PGJ19-2 base, and recognized under ECE standards with additional approval in the United States.
The P21W appears in both the front and rear fog light positions of the Range Rover Sport. It is a single-filament signalling bulb rated at 12V and 21W, using a BA15s bayonet base under ECE standards.
The 2006 front fog light position carries two distinct bulb specifications: H11 for vehicles built after chassis number 6A912927, and H7 for those built up to and including that chassis number. This makes the chassis number a critical factor in determining the correct fitment for that model year.
The H7 bulb, specified for early 2006 Range Rover Sport production, uses a PX26d base and shares the same 12V, 55W rating as the H11. Despite the identical wattage, the two bulbs use different base types and are not interchangeable.
Model years 2007-2009 of the Range Rover Sport list both H11 and P21W as front fog light bulb sizes, indicating that two separate front fog light positions or configurations existed within those years requiring different bulb types.
The rear fog light specification shifted from P21W (2010-2013) to the 5201 bulb (2014-2018). The 5201 is an ANSI-standard single-filament halogen bulb rated at 12V and 19W, fitted with a PG20-1 base, and is specific to the US and Canadian market standard.
The P21W and the 5201 are both single-filament bulbs operating at 12V, but they differ in wattage (21W versus 19W) and base type (BA15s bayonet versus PG20-1). These differences make them non-interchangeable despite their similar application in the rear fog light position.
The H11 and H7 bulbs both operate at 12V and 55W but use entirely different base configurations, PGJ19-2 and PX26d respectively. Substituting one for the other in the 2006 front fog light position without confirming the chassis number would result in an incorrect fitment.
The 5201 bulb follows ANSI standards applicable to the US and Canada, while the H11, H7, and P21W all follow ECE standards recognized across Europe and other global markets. This regulatory distinction reflects differences in the lighting standards under which each bulb type was certified.
