The Maserati Levante high beam and low beam headlight bulbs both use the D3S size. The chart contains bulb size specifications across a 2017 to 2020 replacement range.
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 is a high-intensity discharge (HID) bulb type that operates using xenon gas to produce an arc of light between two electrodes, distinguishing it from conventional halogen filament bulbs.
The Maserati Levante uses the D3S bulb in both the high beam and low beam headlight positions across the 2017-2020 model years.
The D3S designation follows a standardized naming convention where "D" denotes a discharge bulb, "3" refers to the bulb series, and "S" indicates a single-piece construction with the igniter integrated into the bulb body rather than housed separately.
Because the D3S integrates the igniter into the bulb body, it is not interchangeable with D3R bulbs, which share the same base and gas chemistry but carry a reflector-specific coating and are intended for projector-style housings.
The 2020 Levante entries for both beam positions carry the qualifier "With HID Headlamps," indicating that the D3S fitment applies specifically to vehicles equipped with that headlamp configuration.
D3S bulbs operate on a ballast-driven system that requires a high-voltage ignition pulse at startup, meaning the bulb is not a direct drop-in replacement in systems designed for halogen or LED light sources.
The D3S bulb does not contain mercury, which differentiates it from earlier discharge series such as the D1S and D2S, a distinction relevant to disposal regulations in certain regions.
