The Moto Guzzi Sport 1200 uses an H9 bulb size for high beam and H7 bulb size for low beam headlight applications. The replacement chart covers 2006 to 2008 production 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 Moto Guzzi Sport 1200 uses the H9 bulb for high beam and the H7 bulb for low beam across the 2006-2008 model years.
The H9 is a single-filament halogen bulb operating at 12V and 65W, fitted with a PGJ19-5 base, and rated under the ECE standard used in Europe and worldwide, with approval also extended to the US market.
The H7 is a single-filament halogen bulb operating at 12V and 55W, fitted with a PX26d base, and rated under the same ECE standard, with approval covering the US and Japan in addition to Europe.
Because both the H9 and H7 are single-filament designs, each bulb serves only one lighting function, which is why the Sport 1200 requires separate bulbs for high and low beam operation rather than a single dual-filament unit.
The H9 and H7 bulbs draw different wattages, 65W and 55W respectively, meaning the two types are not interchangeable despite sharing a similar physical form factor, as the base configurations differ between PGJ19-5 and PX26d.
The PX26d base of the H7 is among the most widely standardized halogen bases in automotive lighting, while the PGJ19-5 base of the H9 belongs to a distinct family of bases that also includes the H8, H11, and H16 types, though those are separate specifications not listed for this application.
