The INFINITI I35 high beam headlight uses a 9005 bulb size while the low beam headlight requires a D2R bulb size. The replacement chart covers 2002 to 2004 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 9005 is a single-filament halogen bulb operating at 12V and 65W with a P20d base, standardized under the ANSI specification used in the United States and Canada.
The D2R is a high-intensity discharge (HID) xenon bulb rated at 85V and 35W with a P32d-3 base, governed by the ECE standard used in Europe and worldwide markets.
The D2R designation indicates the bulb is designed specifically for reflector-type headlight housings, distinguishing it from the D2S variant, which is intended for projector-type housings.
Unlike halogen bulbs, the D2R requires an external ignitor to initiate and sustain the electrical arc that produces light, making it a more complex system than the 9005.
The Infiniti I35 uses the 9005 for high beam output across the 2002-2004 model years, with the P20d base serving as the physical retention interface in the headlight assembly.
The low beam function on the I35 across the 2002-2004 model years relies on the D2R HID bulb, meaning the low beam system operates on a fundamentally different light-generation technology than the high beam.
The 9005 and D2R bulbs are not interchangeable due to differences in base type, operating voltage, and light-generation method, and each requires a housing and wiring configuration specific to its technology.
