Ferrari 488 GTB high beam and low beam headlight bulbs both use D3S size bulbs. The chart covers replacement bulb specifications across 2016 to 2019 production years.
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 bulb type specified for both the high beam and low beam headlight positions across all listed model years of the Ferrari 488 GTB.
The D3S designation identifies a discharge gas bulb, more commonly known as a High-Intensity Discharge (HID) or xenon bulb, which produces light by passing an electrical arc through xenon gas rather than heating a filament.
The "D" in D3S indicates the bulb belongs to the automotive discharge family, the "3" denotes the third generation of that family, and the "S" specifies a projector-lens housing application, as opposed to the "R" suffix used for reflector housings.
D3S bulbs operate without an external igniter, as the ignition circuitry is integrated directly into the bulb itself, distinguishing them from earlier discharge types such as the D1S.
The Ferrari 488 GTB (2016-2019) uses the D3S specification for both beam functions, meaning a single bulb type serves the full headlight output range rather than separate bulb types for each function.
D3S bulbs are not interchangeable with D1S or D2S units despite sharing a similar physical form, as differences in the integrated igniter and electrical contacts prevent cross-fitting without modification.
The shared D3S fitment across both beam positions across all four listed years indicates a consistent headlight system architecture throughout the 2016-2019 production period of the 488 GTB.
