The Nissan 350Z uses H7 and H1 bulbs for high beam headlights, while low beam headlights require H7 or D2R bulbs depending on configuration. The replacement chart covers 2003 to 2005 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 Nissan 350Z used two distinct headlight systems across the 2003-2005 model years, with halogen and HID (xenon) configurations available depending on the trim or factory-installed headlamp type.
The H7 bulb is a single-filament halogen type operating at 12V and 55W, fitted with a PX26d base. It served as the standard bulb for both high beam and low beam positions on 350Z units without specialized headlamp packages.
The H1 bulb is also a single-filament halogen type rated at 12V and 55W, but uses a P14.5s base rather than the PX26d found on the H7. On the 350Z, it was designated for the high beam position specifically in vehicles equipped with Halogen Capsule Headlamps.
Because the H1 and H7 use different base types, they are not interchangeable despite sharing the same voltage and wattage ratings. Installing the incorrect bulb type in either position is not possible without modification.
The D2R is a high-intensity discharge bulb operating at 85V and 35W, fitted with a P32d-3 base. It was specified for the low beam position on 350Z vehicles equipped with HID headlamps.
The D2R designation indicates compatibility with reflector-type housings specifically, distinguishing it from the D2S variant, which is intended for projector-type housings. These two types are not interchangeable.
Unlike halogen bulbs, the D2R requires an external ignitor to initiate the high-voltage arc necessary for operation. This component is part of the HID headlamp assembly and is not present in halogen-equipped vehicles.
All three bulb types, H7, H1, and D2R, conform to ECE standards and carry approval for use in the United States and Japan, reflecting their broad regulatory acceptance across major automotive markets.
