Lamborghini Aventador high beam and low beam headlight bulbs both use D3S size bulbs. The chart covers replacement bulb specifications across 2012 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 Lamborghini Aventador uses the D3S bulb type for both high beam and low beam headlights across all listed model years from 2012-2019.
The D3S is a High-Intensity Discharge (HID) bulb, meaning it produces light through an electrical arc between two tungsten electrodes rather than a heated filament.
The "D" prefix in D3S designates a discharge-type bulb, while the "S" suffix indicates it has a shroud, which is a UV-blocking quartz or glass enclosure built directly around the arc tube.
The shroud on the D3S is an integral part of the bulb's construction, and its presence is a defining fitment characteristic that distinguishes it from the D3R, which uses a reflector-based housing instead.
Because the D3S is mercury-free, it does not share direct interchangeability with older HID standards such as the D1S or D2S, which contain mercury and operate on different ballast voltages.
The D3S operates on a 42-volt system and requires a compatible ballast to regulate the high-voltage ignition pulse needed to strike the arc and the lower sustaining voltage used during normal operation.
Since the same D3S bulb size is specified for both the high beam and low beam positions on the Aventador, the vehicle relies on a projector or shutter-based optical system to switch between beam patterns rather than separate bulb types.
Substituting a non-shrouded HID bulb in a housing designed for the D3S shrouded type can result in improper light distribution and potential glare, as the optical system is calibrated around the shroud's light-blocking properties.
