The Ducati 1000 front turn signal bulb uses a 5008 size, while rear turn signal bulbs use either 5008 or 232 sizes. The replacement chart covers 2003 through 2006 model years 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 1000 uses the 5008 bulb as the dominant turn signal type across both front and rear positions for the 2003-2006 model years.
The 5008 is an ANSI-standard single-filament bulb with a BA15s bayonet base, rated at 12V, and is classified as a lower wattage variant of the 1156.
The BA15s bayonet base features a single contact pin, which is a defining characteristic of single-filament applications such as turn signals.
The rear turn signal for the 2005 model year takes a 232 bulb rather than the 5008 used in all other listed years for that position.
The 232 is a festoon-type bulb with an SV8.5 base, rated at 12V and 3W, and differs fundamentally in both form factor and mounting style from the BA15s bayonet base of the 5008.
A festoon bulb is cylindrical in shape and seats by pressing its end caps into spring clips, making it physically incompatible with a bayonet socket designed for the 5008.
The front turn signal position uses the 5008 consistently across all four listed model years, 2003-2006, without variation.
Because the 5008 and 232 use entirely different base types, the two bulbs are not interchangeable regardless of voltage compatibility.
