The Ducati Desmosedici RR uses H11 bulbs for both high beam and low beam headlight applications, with this specific bulb size applying to the model's headlight assembly. The replacement chart covers 2007 to 2008 production years and details the corresponding bulb size specifications for each headlight function.
The year-by-year compatibility chart below provides a quick reference to verify the correct bulb size for your vehicle.
The H11 bulb type is used across all listed headlight positions on the Ducati Desmosedici RR, covering both high beam and low beam functions for the 2007-2008 model years.
The H11 is a single-filament halogen bulb operating at 55 watts with a PGJ19-2 base. It belongs to the H-series of automotive halogen bulbs defined under ECE regulations.
The use of the same H11 bulb for both high beam and low beam positions indicates that the Desmosedici RR headlight system relies on separate physical housings or projector units for each function rather than a dual-filament bulb to switch between modes.
Because the high beam and low beam share the same bulb type, a single H11 replacement bulb is compatible with either position on the 2007-2008 Desmosedici RR.
The H11 bulb produces a focused, low-glare output, which is consistent with its widespread use in projector-style headlight assemblies found on performance motorcycles.
The H11 base is not interchangeable with the physically similar H8 or H9 bases despite sharing the same PGJ19 family designation, as the locking tab positions differ between variants.
