Bentley Flying Spur high beam and low beam headlight bulbs both utilize D3S size bulbs for optimal illumination. The replacement chart covers 2015 to 2020 model 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 Bentley Flying Spur across both high beam and low beam headlight positions for the 2015-2020 model years, and it applies exclusively to vehicles equipped with HID headlamps.
The D3S is a high-intensity discharge (HID) xenon bulb rated at 42 volts and 35 watts, operating on the principle of an electrical arc through xenon gas rather than a heated filament.
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 within the headlamp assembly.
The D3S uses a PK32d-5 base, which is a keyed connector designed specifically for projector-type headlamp housings, making it physically incompatible with reflector-type housings that use different base configurations.
The D3S is formulated without mercury, conforming to environmental regulations that restrict hazardous substances in electrical components under ECE standards applicable in Europe and numerous other markets worldwide.
Because both the high beam and low beam positions on the Flying Spur (2015-2020) share the same D3S specification, the vehicle uses a projector-type housing capable of producing both beam patterns from a single bulb per headlamp unit.
The HID headlamp condition noted in the specifications indicates a trim or factory-installed option dependency, meaning the D3S fitment is contingent on the vehicle being factory-equipped with HID headlamps rather than an alternative headlamp system.
