The Ducati Multistrada 620 headlight bulb uses H7 size for both high beam and low beam functions. The replacement chart covers 2005 to 2006 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 a single-filament halogen type operating at 55 watts with a PX26d base, designed for use in projector or reflector housings that require a dedicated bulb per function rather than a dual-filament arrangement.
The Ducati Multistrada 620 uses the H7 bulb for both the high beam and low beam headlight positions across the 2005-2006 model years.
Because both beam positions share the same H7 specification, the motorcycle carries two separate H7 bulbs in its headlight assembly rather than a single dual-filament unit handling both functions.
The H7 format is standardized under ECE Regulation 37, meaning bulbs from different manufacturers are physically interchangeable as long as they conform to that standard and carry the correct wattage rating.
Although the H7 base is uniform, substituting a bulb with a higher wattage than the factory 55-watt rating can exceed the thermal and electrical tolerances of the original housing and wiring.
The PX26d base of the H7 bulb is a keyed single-pin connector, which prevents incorrect orientation during installation and ensures consistent filament positioning relative to the reflector focal point.
