Additional Notes

The 9003 bulb, used in the Infiniti G35 high beam headlight for 2003-2005, is a dual-filament halogen type rated at 12V with a 60W high beam filament and a 55W low beam filament. Its P43t base follows the ANSI standard applicable in the US and Canada.
The D2S and D2R bulbs are both HID (xenon) discharge types operating at 85V and 35W, but they are not interchangeable. The D2S carries a P32d-2 base and is designed for projector-type housings, while the D2R carries a P32d-3 base and is designed for reflector-type housings.
Both D2S and D2R bulbs require an external ignitor, which is a separate component that generates the high-voltage pulse needed to initiate the xenon arc discharge. Neither type operates directly from standard automotive low-voltage circuits without this component.
The 2008 G35 low beam headlight position lists two bulb sizes, D2S and 9006, indicating that two distinct headlight configurations were available for that year, each requiring a different bulb type.
The H1 bulb, specified for the G35 low beam headlight on 2003-2005 models with halogen capsule headlamps, is a single-filament halogen type rated at 12V and 55W. It uses a P14.5s base and follows the ECE standard, though it also holds approval in the US and Japan.
The 9006 bulb, listed for the 2008 G35 low beam, is a single-filament halogen type rated at 12V and 55W with a P22d base. Despite sharing the same wattage as the H1, the two bulbs use different base types and are not interchangeable.
For 2003-2005 G35 models, the low beam headlight fitment depends on the headlamp system installed. Vehicles with halogen capsule headlamps take the H1 bulb, while those with HID headlamps take the D2R bulb. Substituting one for the other is not supported by the specifications.
The D2S bulb follows the ECE standard, which governs lighting equipment in Europe and other worldwide markets. Its use in the 2008 G35 high beam and one of the 2008 low beam configurations reflects the adoption of ECE-standard components outside of their region of origin.
