The Aston Martin Rapide high beam and low beam headlight bulbs both use the D1S size. The chart contains replacement bulb specifications covering 2011 to 2019.
The year-by-year compatibility chart below provides a quick reference to verify the correct bulb size for your vehicle.
The Aston Martin Rapide uses the D1S bulb type for both high beam and low beam headlights across all model years from 2011-2019.
The D1S is a discharge bulb, meaning it operates on high-voltage arc technology rather than a heated filament, which places it in the High-Intensity Discharge (HID) category.
D1S bulbs have a self-contained igniter integrated into the bulb base, distinguishing them from D2S bulbs, which require a separate external igniter module.
The "S" designation in D1S refers to a projector-style housing, indicating the Rapide's headlight assemblies use projector optics rather than reflector-style housings.
Because the D1S integrates its igniter, substituting a D2S bulb is not a direct swap, as the two types are electrically and physically incompatible despite sharing similar light output characteristics.
The D1S standard specifies a color temperature of approximately 4200K, producing a white light with a slight blue tint compared to halogen bulbs.
The identical D1S fitment across both high beam and low beam positions on the Rapide means the vehicle uses a single bulb type to serve both functions, typically achieved through a bi-xenon projector system that mechanically shifts the beam pattern.
The consistent D1S specification across the full 2011-2019 model range indicates no headlight system changes were introduced that would affect bulb compatibility between those years.
