The Ducati Diavel high beam headlight uses an H1 bulb size while the low beam headlight requires an H7 bulb size. The replacement chart covers vehicle production years spanning 2011 to 2014 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 Ducati Diavel uses the H1 bulb type for the high beam headlight across the 2011-2014 model years. The H1 is a single-filament halogen bulb with a P14.5s base, commonly rated at 55 watts and operating at 12 volts.
The H7 bulb type is specified for the low beam headlight across the same 2011-2014 range. The H7 is also a single-filament halogen bulb, using a PX26d base, and is typically rated at 55 watts at 12 volts.
The Ducati Diavel uses two distinct bulb types simultaneously, with the H1 and H7 serving separate functions within the headlight assembly. These two bulb types are not interchangeable with each other, as they differ in base design and pin configuration.
The H1 and H7 bulbs share a similar wattage rating in standard form but are physically incompatible due to their different base types. Substituting one for the other in the Diavel's headlight housing is not possible without modification.
Both the H1 and H7 specifications remain consistent across all four model years covered, indicating no bulb type changes occurred in the Ducati Diavel headlight assembly between 2011 and 2014.
