The Ducati PaulSmart 1000 LE headlight bulb uses a 9003 size for both high 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 9003 bulb type is the sole bulb standard listed across all headlight positions in the Ducati PaulSmart 1000 LE specifications, covering both the high beam and low beam functions for the 2005-2006 model years.
The 9003 bulb is a dual-filament halogen type, meaning a single bulb physically contains two separate filaments, one dedicated to high beam output and one to low beam output.
Because the 9003 serves both beam functions in the Ducati PaulSmart 1000 LE, the high beam and low beam housings accept the same bulb unit, which simplifies parts sourcing since only one bulb type is required for both positions.
The 9003 standard is electrically and physically equivalent to the H4 bulb designation used in many international markets, meaning H4-labeled bulbs are generally interchangeable with those marked 9003.
The 9003/H4 bulb operates on a nominal 12-volt electrical system and is rated at 60 watts on the high beam filament and 55 watts on the low beam filament under standard specifications.
The 9003 bulb uses a P43t base, which is a three-pronged bayonet-style mount. This base type is specific to the H4/9003 family and is not compatible with single-filament bulb sockets such as those designed for H1 or H7 types.
Because the same 9003 fitment applies to both beam positions across both listed model years, there are no year-specific or position-specific variations to account for when sourcing a replacement bulb for the 2005-2006 PaulSmart 1000 LE.
