The Ferrari California high beam and low beam headlight bulbs both utilize a D3S size specification. The replacement chart covers vehicle production spanning 2009 to 2014.
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 Ferrari California uses the D3S bulb type across both its high beam and low beam headlight positions for the full 2009-2014 model range.
The D3S is a high-intensity discharge (HID) xenon bulb, meaning it produces light by creating an electrical arc through xenon gas rather than heating a filament.
D3S bulbs operate at 42 volts and 35 watts, which are standard values for automotive HID systems and reflect the high-voltage ignition requirements of discharge lighting technology.
The D3S carries the ECE standard designation, indicating it meets European and international regulatory requirements for road use.
A defining characteristic of the D3S is its integral ignitor, meaning the ignition component is built directly into the bulb unit rather than housed separately in the vehicle's lighting system.
The D3S uses a PK32d-5 base, which is a keyed connector format specific to this bulb family and is not interchangeable with bases found on other HID bulb types such as the D1S or D2S.
The D3S is a mercury-free formulation, distinguishing it from earlier HID standards like the D1S and D2S, which contain mercury as part of their arc tube chemistry.
The Ferrari California's use of the D3S in projector-type housings reflects the optical design requirement of that bulb, as D3S bulbs are specified for projector housings rather than reflector-type assemblies.
