Land Rover Range Rover Headlight Bulb Size

Additional Notes

• The D3S bulb is the most consistently specified type across the Land Rover Range Rover headlight data, appearing in both high beam and low beam positions from 2010 through 2019. It is a high-intensity discharge (HID) bulb that operates without an ignition electrode, relying instead on a pre-existing arc, and it contains no mercury, which distinguishes it from earlier HID standards.
• The H7 bulb appears frequently in both high beam and low beam positions across the 2003-2012 model years, with some overlap depending on trim configuration. It is a single-filament halogen bulb rated at 55 watts, using a PX26d base, and it is not interchangeable with dual-filament bulb types despite its widespread use across many vehicle platforms.
• The 9005 bulb is specified for high beam use on the Range Rover from 1996-2002. It is a single-filament halogen bulb with an HB3 designation and a P20d base, producing a relatively high lumen output suited to dedicated high beam applications. It is not compatible with low beam housings designed for other base types.
• The 9003 bulb, specified for low beam use from 1996-2002, is a dual-filament halogen bulb equivalent to the H4 standard. Because it carries both high and low beam filaments within a single envelope, it is not interchangeable with the single-filament 9005 used in the high beam position during the same years.
• The H6024 bulb is listed for both high and low beam positions on the 1987, 1988, and 1994 Range Rover. It is a sealed-beam unit, meaning the lens, reflector, and filament are fused into one non-serviceable assembly. Sealed-beam units are replaced as a whole rather than by bulb alone, which is a fundamental fitment difference from all other bulb types in these specifications.
• The 2009 Range Rover high beam position lists both H7 and H8 as possible sizes, indicating that two distinct headlamp assemblies were fitted to that model year. The H8 is a single-filament halogen bulb with a PGJ19-1 base and is not interchangeable with the H7, which uses a PX26d base, despite their similar physical appearance.
• For the 2003-2005 low beam position, the Range Rover is listed with either H7 or D2S depending on whether the vehicle was equipped with halogen capsule headlamps or HID headlamps. The D2S is a discharge bulb requiring a ballast and high-voltage igniter, making it entirely incompatible with halogen headlamp housings. Substituting one type for the other without a full housing change is not supported by these specifications.
• The 2006-2008 low beam position similarly lists both H7 and D1S as options. The D1S integrates its igniter directly into the bulb body, unlike the D2S, which uses an external igniter. Although D1S and D2S are both HID types, they are not interchangeable with each other due to differing base designs and ignition configurations.
• From 2010 onward, the high beam position transitions fully to D3S, replacing the H7 that appeared alongside D3S in 2010-2012. This means that for the 2010-2012 Range Rover, two different high beam bulb types are listed, reflecting the presence of more than one headlamp system across the production run of those years.
• The Land Rover Range Rover low beam specifications show no D3S fitment before 2010, while the high beam specifications show D3S appearing as early as 2011 alongside H7. This means that for certain years, the high beam and low beam positions require different bulb types even when both are part of an HID-equipped system, and cross-position substitution would not be appropriate.
