The INFINITI M35 high beam headlight uses a 9005 bulb size while low beam headlights require D2S or H1 bulb sizes for proper illumination. The replacement chart covers 2006 to 2010 model years 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 9005 bulb is a single-filament halogen type rated at 12V and 65W, built to the ANSI standard used in the United States and Canada. It uses a P20d base and serves as the high beam headlight bulb across all five model years covered by the Infiniti M35 specifications, spanning 2006-2010.
The D2S is a high-intensity discharge (HID) xenon bulb rated at 85V and 35W, built to the ECE standard used in Europe and worldwide. It uses a P32d-2 base and is designed specifically for projector-type housings. Unlike halogen bulbs, the D2S requires an external ignitor to initiate and sustain the electrical arc that produces light.
The H1 is a single-filament halogen bulb rated at 12V and 55W, built to the ECE standard but also approved for use in the United States and Japan. It uses a P14.5s base and is a distinct type from the 9005, meaning the two are not interchangeable despite both being single-filament halogen bulbs.
For the 2009-2010 Infiniti M35, the low beam headlight position uses only the D2S bulb, indicating that HID projector-type headlamps were standard for those years with no halogen alternative listed.
For the 2006-2008 model years, the low beam headlight position accommodates either an H1 or a D2S bulb depending on the headlamp system installed. Vehicles equipped with halogen capsule headlamps use the H1, while those equipped with HID headlamps use the D2S.
Because the H1 and D2S bulbs serve the same low beam position on 2006-2008 vehicles but are electrically and mechanically incompatible with each other, the correct bulb type is determined by the specific headlamp assembly installed on the vehicle rather than the model year alone.
