Land Rover Range Rover Sport high beam and low beam headlight bulbs use D3S, H7, or D2S sizes depending on production specifications. The chart covers 2006 to 2019 model years with corresponding bulb size replacements for each generation.
The year-by-year compatibility chart below provides a quick reference to verify the correct bulb size for your vehicle.
ECE standard (Europe & worldwide). Mercury-free HID (xenon) discharge bulb with PK32d-5 base and integral ignitor, for projector-type housings. 42V, 35W.
The D3S and H7 are the two bulb types that appear across the high beam and low beam headlight specifications for the Land Rover Range Rover Sport, with D2S listed as an additional option for the 2006 model year when equipped with HID headlamps.
The D3S is a high-intensity discharge (HID) bulb that operates without a separate ignition module, as the igniter is built directly into the bulb housing. It runs on alternating current and produces light through an electrical arc between two tungsten electrodes within a xenon gas-filled quartz capsule.
The H7 is a halogen bulb with a two-pin PX26d base. It operates on a single filament and is widely used in projector and reflector headlight housings. H7 bulbs are not interchangeable with HID or discharge-type bulbs such as the D3S or D2S without significant modification to the housing and electrical system.
The D2S is also an HID discharge bulb, but unlike the D3S, it requires an external igniter as part of the ballast assembly. The D2S and D3S are not directly interchangeable due to differences in their ignition systems and base configurations.
For the 2015-2019 Range Rover Sport, both the high beam and low beam headlights use the D3S bulb exclusively, indicating a standardized HID lighting system across those model years.
The 2014 Range Rover Sport uses the H7 bulb for both high beam and low beam positions, making it the only single model year in the 2010s portion of the specifications where halogen is the sole listed option for both functions.
The 2010-2013 model years list both D3S and H7 as high beam options, reflecting that multiple headlight system configurations were available during those years. The low beam for 2010-2013 lists only the D3S, which means the H7 high beam entries correspond to trim levels or packages with a different headlight assembly than those using D3S low beams.
The 2006 model year is the only one in the specifications to list the D2S bulb, and it is explicitly noted as applying to vehicles equipped with HID headlamps. The standard 2006 configuration uses the H7 for both high and low beam positions.
The 2006-2009 Range Rover Sport high beam and low beam positions share the same bulb type within each configuration, with H7 serving both functions in the standard setup and D2S serving both in the HID variant for 2006.
Because the D3S, D2S, and H7 operate on fundamentally different electrical and optical principles, substituting one type for another requires changes beyond the bulb itself, including compatibility with the vehicle's ballast, wiring harness, and headlight housing design.
