The INFINITI FX35 high beam and low beam headlight bulbs both utilize a D2S bulb size for xenon HID lighting systems. The replacement chart covers vehicle production spanning from 2003 to 2012 with corresponding bulb specifications.
The year-by-year compatibility chart below provides a quick reference to verify the correct bulb size for your vehicle.
The Infiniti FX35 uses the D2S bulb type for both high beam and low beam headlights across all model years from 2003-2012.
The D2S is a High-Intensity Discharge (HID) xenon bulb, meaning it produces light by creating an electrical arc through xenon gas rather than heating a filament.
D2S bulbs operate at 85 volts and 35 watts, which reflects the high-voltage ignition requirement typical of HID technology before the arc stabilizes to a lower operating voltage.
The D2S uses a P32d-2 base, a standardized fitting specific to HID projector applications, and is not physically interchangeable with halogen base types such as H1, H7, or H11.
D2S bulbs are designed exclusively for projector-type housings, and their use in reflector-style housings produces uncontrolled light scatter that reduces visibility and increases glare for oncoming traffic.
The D2S requires an external ignitor to generate the initial high-voltage pulse needed to strike the arc, meaning the ignitor is a separate component from the bulb itself.
The D2S conforms to ECE regulations, a standard recognized across Europe and many other markets worldwide, which governs the bulb's output, color temperature range, and dimensional tolerances.
Because both the high beam and low beam positions on the FX35 share the D2S specification, the vehicle relies on the projector housing's internal shutter mechanism to switch between beam patterns rather than using separate bulbs for each function.
