Bentley Continental high beam and low beam headlight bulbs both utilize D3S size specifications. The replacement chart covers vehicle production spanning 2015 to 2020.
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 bulb type is specified for both high beam and low beam headlight positions across the Bentley Continental for model years 2015-2020.
The D3S is a High-Intensity Discharge (HID) xenon bulb rated at 42 volts and 35 watts, operating on the ECE standard recognized in Europe and worldwide.
A defining characteristic of the D3S is its built-in ignitor, which is integrated directly into the bulb body rather than housed separately in the vehicle's lighting system.
The D3S uses a PK32d-5 base, a configuration specific to discharge bulbs with integrated ignitors, making it physically incompatible with sockets designed for bulbs that rely on external ignitors.
The D3S is a mercury-free formulation, distinguishing it from earlier HID bulb generations that contained mercury as part of the arc discharge medium.
The specifications apply only to Bentley Continental vehicles equipped with HID headlamps, indicating that this fitment condition is a prerequisite for the D3S application.
Because the D3S is designed for projector-type housings, substituting it into reflector-style housings would produce incorrect light distribution regardless of electrical compatibility.
