The Lamborghini Gallardo high beam and low beam headlight bulb sizes include D1S and D2S options, with each bulb size corresponding to specific vehicle configurations. The replacement chart covers 2004 through 2014 production years and details the bulb size specifications for each model year.
The year-by-year compatibility chart below provides a quick reference to verify the correct bulb size for your vehicle.
Both the high beam and low beam headlights on the Lamborghini Gallardo use HID (xenon) discharge bulbs across all listed model years, operating at 85V and 35W regardless of the specific bulb type fitted.
The Gallardo uses two distinct HID bulb types across its production span: the D1S for model years 2009-2014 and the D2S for model years 2004-2008, with both the high beam and low beam positions following the same year-based split.
The D1S bulb carries a PK32d-2 base and incorporates an integral ignitor as part of the bulb unit itself, meaning the ignition component is replaced along with the bulb during servicing.
The D2S bulb uses a P32d-2 base and requires a separate external ignitor, which remains in the housing when the bulb is replaced. The base designation differs from the D1S, making the two types physically non-interchangeable.
Both bulb types conform to the ECE standard, a regulatory framework recognized across Europe and numerous other markets worldwide, governing output, color temperature, and fitment tolerances for automotive lighting.
Both the D1S and D2S are designed exclusively for projector-type headlight housings, which use a lens and reflector assembly to focus and shape the light output, as opposed to reflector-type housings.
Because the D1S and D2S share the same 85V and 35W electrical ratings but differ in base type and ignitor configuration, substituting one for the other is not supported by the specifications, even within the same vehicle model across different years.
