The Ducati 998 front turn signal requires a 5008 bulb size, while rear turn signals use either 232 or 5008 bulb sizes. The replacement chart covers 2002 to 2004 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 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 232 is an ANSI-standard festoon bulb with an SV8.5 base, rated at 12V and 3W.
The BA15s bayonet base of the 5008 is a single-contact base, meaning it is not interchangeable with dual-contact BA15d variants without modification.
The Ducati 998 front turn signal uses the 5008 bulb across the 2002-2004 model years.
The rear turn signal specification for the 2004 Ducati 998 differs from earlier model years, using the 232 festoon bulb rather than the 5008.
The rear turn signal on the 2002-2003 998 uses the 5008, making front and rear bulbs identical for those years, while the 2004 model requires a separate bulb type for the rear position.
The festoon form factor of the 232 bulb is physically distinct from the BA15s bayonet form factor of the 5008, and the two bulb types are not interchangeable.
