The Ferrari California T high beam and low beam headlight bulbs both utilize the D3S size. The replacement chart covers 2015 to 2017 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 D3S is the sole bulb type specified for the Ferrari California T across both high beam and low beam headlight positions for the 2015-2017 model years.
The D3S is a high-intensity discharge (HID) bulb that operates within a projector-style housing and contains no separate outer glass envelope, with the arc tube exposed directly to the reflector or lens assembly.
D3S bulbs operate on a self-contained ballast-integrated system and do not require mercury in their construction, which distinguishes them from earlier HID types such as the D2S.
The D3S designation follows a standardized IEC naming convention: "D" denotes a discharge bulb, "3" identifies the generation and base type, and "S" indicates compatibility with projector-style housings rather than reflector housings.
Because the Ferrari California T uses D3S bulbs in both the high beam and low beam positions for 2015-2017, the vehicle relies entirely on HID technology for its primary forward lighting rather than a combination of HID and halogen sources.
D3S bulbs are not cross-compatible with D1S or D2S sockets due to differences in the base configuration and igniter placement, making direct substitution with those types physically impossible without modification.
The D3S bulb type produces a color temperature typically in the range of 4200K to 6000K depending on the manufacturer, which corresponds to a white to cool-white light output.
