Land Rover Discovery Sport headlight bulbs utilize D3S and H15 sizes for high beam applications, while low beam functions require D3S and H11 bulb sizes. The replacement chart covers 2015 through 2019 production 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.
ECE standard (Europe & worldwide). Mercury-free HID (xenon) discharge bulb with PK32d-5 base and integral ignitor, for projector-type housings. 42V, 35W.
The Land Rover Discovery Sport (2015-2019) is equipped with one of two distinct headlamp systems: HID (High-Intensity Discharge) or Halogen Capsule, and the correct bulb type depends entirely on which system is installed in the vehicle.
The D3S is the bulb type used in both the high beam and low beam positions on HID-equipped Discovery Sport models across all listed years. It operates at 42V and 35W, uses a PK32d-5 base with an integral ignitor, and is designed specifically for projector-type housings.
The D3S is a mercury-free xenon discharge bulb that produces light through an electrical arc rather than a heated filament, which distinguishes it fundamentally from the halogen types listed alongside it.
On halogen-equipped Discovery Sport models, the high beam and low beam positions use different bulb types, meaning the two positions are not interchangeable with each other. The high beam uses the H15, while the low beam uses the H11.
The H15 is a dual-filament halogen bulb rated at 12V with a 55W/15W output, using a PGJ23t-1 base. The two wattage values correspond to its two filaments, which serve separate lighting functions within a single bulb.
The H11 is a single-filament halogen bulb rated at 12V and 55W, using a PGJ19-2 base. Unlike the D3S, it carries approval under both ECE standards and US regulations.
All three bulb types listed, the D3S, H15, and H11, conform to ECE standards, indicating they are rated for use in Europe and worldwide markets.
The base types across the three bulbs, PK32d-5, PGJ23t-1, and PGJ19-2, are physically distinct and incompatible with one another, meaning no substitution between bulb types is possible regardless of wattage similarity.
