The Ducati Monster 1000 front turn signal requires a 5008 or 232 bulb size, while the rear turn signal uses a 5008 bulb size. The replacement chart covers 2003 to 2005 production 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 5008 is an ANSI-standard single-filament bulb with a BA15s bayonet base, rated at 12V, and is considered a lower wattage variant of the more widely known 1156 bulb.
The 232 is an ANSI-standard festoon bulb with an SV8.5 base, rated at 12V and 3W. Festoon bulbs are cylindrical in form and seat by pressing between two spring contacts rather than inserting into a socket.
Both the 5008 and 232 are ANSI standards recognized in the US and Canada.
The Ducati Monster 1000 uses two distinct bulb types across its front turn signal positions depending on the model year. The 2005 front turn signal takes a 5008, while the 2003-2004 front turn signals take a 232.
The BA15s bayonet base of the 5008 and the SV8.5 base of the 232 are physically incompatible with each other, meaning the front turn signal housing changed between the 2004 and 2005 model years.
The rear turn signal on the Monster 1000 uses the 5008 across all three model years covered, spanning 2003-2005.
Because the front and rear turn signals share the same 5008 bulb on the 2005 model, only one bulb type is required across all four turn signal positions that year.
On 2003-2004 models, the front and rear turn signals require different bulb types, making the front 232 and rear 5008 non-interchangeable despite both being 12V bulbs.
