The Ducati Sport 1000 high beam and low beam headlight bulbs both utilize a 9003 bulb size for optimal illumination. The replacement chart covers vehicle production spanning 2007 to 2009 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 9003 bulb type is specified for both the high beam and low beam headlight positions across all listed model years of the Ducati Sport 1000, covering the 2007-2009 production range.
The 9003 bulb is a dual-filament halogen type, meaning a single bulb unit contains two separate filaments, one dedicated to high beam output and one to low beam output.
Because the Sport 1000 uses the 9003 specification for both headlight positions, the same physical bulb serves both functions within the headlight assembly rather than requiring separate single-filament bulbs for each beam.
The 9003 standard is the international designation for what is also commonly sold under the HB2 designation, and both refer to the same bulb with identical electrical and physical characteristics.
The 9003 bulb operates at a rated wattage of 60 watts on the high beam filament and 55 watts on the low beam filament, with a standard operating voltage of 12 volts.
The 9003 uses a P43t base, which is a three-pronged bayonet-style mount. This base type is specific to the 9003 and HB2 family and is not interchangeable with other common motorcycle headlight bases such as the H4's P43t-38 variant without confirming exact socket compatibility.
Although the 9003 and H4 bulbs are frequently referenced together due to their similar dual-filament design, they are not universally interchangeable, as differences in base alignment and pin positioning can affect fitment depending on the specific headlight housing.
