Porsche Panamera high beam headlight bulbs use H7 size while low beam headlight bulbs use D1S size. The replacement chart covers 2010 to 2016 vehicle production 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 H7 is a single-filament halogen bulb operating at 12V and 55W, fitted with a PX26d base. It holds ECE certification for use in Europe and worldwide markets, and carries approval in the United States and Japan as well.
The D1S is a high-intensity discharge xenon bulb operating at 85V and 35W, fitted with a PK32d-2 base. Unlike many HID types, the D1S incorporates an integral ignitor within the bulb body itself, and it is designed specifically for projector-type headlamp housings.
The Porsche Panamera uses the D1S for low beam across all model years from 2010-2016, making it the discharge-type bulb throughout the entire production span covered by these specifications.
The H7 serves as the high beam bulb across all model years from 2010-2016. Its halogen technology operates independently from the D1S low beam system, meaning the two positions rely on fundamentally different lighting technologies within the same headlamp assembly.
For the 2014-2016 Panamera, both the H7 high beam and D1S low beam entries carry a "With HID Headlamps" qualifier, indicating that this fitment applies specifically to vehicles equipped with the HID headlamp configuration.
The D1S integral ignitor design means the ignitor and bulb are replaced as a single unit, which differs from HID systems where the ignitor is housed separately within the ballast assembly.
The H7 PX26d base is a keyed, single-pin connector that prevents incorrect bulb installation. Its physical configuration is not interchangeable with other common halogen bases such as H1 or H4, despite those bulbs sharing similar wattage ratings.
The D1S PK32d-2 base is specific to the D1S type and is not physically compatible with other D-series HID bulbs such as the D2S or D3S, which use different base configurations and voltage requirements.
