The Acura ZDX uses a 9005 bulb size for high beam headlight operation and a D2S bulb size for low beam headlight operation. The replacement chart covers 2010 through 2013 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.
The Acura ZDX uses the 9005 bulb for high beam headlights across all model years from 2010-2013.
The 9005 is a single-filament halogen bulb operating at 12V and 65W, built to the ANSI standard used in the United States and Canada, and fitted with a P20d base.
Low beam headlights on the Acura ZDX use the D2S bulb for all model years from 2010-2013.
The D2S is a high-intensity discharge (HID) xenon bulb rated at 85V and 35W, built to the ECE standard recognized in Europe and internationally, and fitted with a P32d-2 base.
The D2S bulb is designed specifically for projector-type housings and requires an external ignitor to initiate the electrical arc that produces light, making it incompatible with standard reflector housings without additional components.
The high beam and low beam circuits on the ZDX use fundamentally different bulb technologies, halogen for high beams and HID for low beams, meaning the two positions are not interchangeable.
The P20d base of the 9005 and the P32d-2 base of the D2S are physically distinct, which prevents accidental cross-installation between the two bulb types.
Because the D2S operates at 85V rather than the 12V supply voltage of the vehicle's electrical system, the external ignitor and ballast are required components of the low beam circuit rather than optional additions.
