The Ducati 1098 headlight uses an H11 bulb size for both high beam and low beam functions. The replacement chart covers 2007 to 2009 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 H11 bulb type appears across all listed years (2007-2009) of the Ducati 1098 for both high beam and low beam headlight positions.
The H11 is a single-filament halogen bulb operating at 55 watts on a 12-volt system, belonging to the PGJ19-2 base family, which uses a twist-and-lock mounting mechanism.
The use of the same H11 bulb for both the high beam and low beam positions on the Ducati 1098 indicates a projector-style or dual-housing headlight system where each function is handled by a separate dedicated bulb rather than a dual-filament unit.
Because the high beam and low beam positions share the same H11 specification across the 2007-2009 model years, a single bulb type satisfies both replacement needs on this motorcycle.
The H11 bulb is not interchangeable with the physically similar H8 or H9 variants despite sharing the same base type, as wattage and lumen output differ between them, which is relevant when sourcing replacements.
Aftermarket H11 bulbs are widely produced in halogen, HID conversion, and LED formats, though non-halogen alternatives may require additional components such as ballasts or relay harnesses to function correctly in the original housing.
