The Ducati Multistrada 1100 headlight bulb sizes include H9 and H7 for high beam applications and H1 and H7 for low beam applications. 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 H7 bulb is the most frequently referenced type across these specifications, appearing in both high beam and low beam positions for the Ducati Multistrada 1100 in 2007-2008.
The H7 is a single-filament halogen bulb operating at 55 watts with a PX26d base, designed for dedicated single-function lamp housings rather than dual-function applications.
In 2007-2008, the high beam and low beam headlights share the same H7 bulb type, meaning both positions draw from the same bulb specification during those years.
The 2009 model year represents a departure from the H7 configuration, with the high beam position switching to an H9 and the low beam position switching to an H1.
The H9 bulb, specified for the 2009 high beam, is a single-filament halogen type rated at 65 watts with a PGJ19-5 base, producing notably higher output than the H7 it replaced in that position.
The H1 bulb, specified for the 2009 low beam, uses a single filament and a P14.5s single-pin base, a base type physically distinct from both the H7 and H9, making cross-substitution between these types mechanically incompatible.
Because the 2009 high beam uses an H9 and the 2008 high beam uses an H7, these two model years require different replacement bulbs for that position despite sharing the same vehicle nameplate.
The H9 and H7 bulbs share the same PGJ19 base family, and while some sources note a degree of physical similarity, their wattage ratings and intended operating conditions differ, and substitution between them is not supported by these specifications.
