The INFINITI EX35 high beam headlight uses an H9 bulb size, while low beam headlight applications require either H11 or D2S bulb sizes depending on configuration. The replacement chart covers 2008 through 2012 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 Infiniti EX35 uses the H9 bulb for high beam headlights across all model years from 2008-2012. The H9 is a single-filament halogen bulb operating at 12V and 65W, built to ECE standards and also approved for use in the United States. It uses a PGJ19-5 base.
The low beam headlight position on the EX35 accommodates two distinct bulb types depending on the headlamp system installed at the factory. This split applies uniformly across all model years from 2008-2012.
Vehicles equipped with halogen capsule headlamps use the H11 bulb for low beam output. The H11 is a single-filament halogen bulb with a PGJ19-2 base, rated at 12V and 55W. It conforms to ECE standards and carries US approval.
Vehicles equipped with HID headlamps use the D2S bulb for low beam output. The D2S is a high-intensity discharge xenon bulb rated at 85V and 35W, designed specifically for projector-type housings and requiring an external ignitor to operate.
The H9 and H11 bulbs share a single-filament halogen construction but use different base types, PGJ19-5 and PGJ19-2 respectively, making them non-interchangeable despite their similar appearance and voltage rating.
The D2S bulb operates at 85V, a significantly higher voltage than the 12V halogen bulbs used elsewhere in the EX35 headlamp system. This difference reflects the arc-discharge ignition process that xenon bulbs rely on rather than a heated tungsten filament.
Because the low beam position accepts either H11 or D2S depending on the installed headlamp type, the correct replacement bulb for any individual EX35 is determined by whether that vehicle left the factory with halogen capsule or HID headlamps.
The D2S designation indicates compatibility with projector-style housings only. Installing a D2S bulb in a reflector housing, or substituting an H11 in a system designed for HID, would represent a fitment mismatch outside the scope of these specifications.
