The Ducati 748 SPS uses a 232 bulb size for front turn signals and a 5008 bulb size for rear turn signals. The replacement chart covers 1998 to 1999 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 Ducati 748 SPS uses two distinct bulb types across its turn signal positions: the 232 for the front and the 5008 for the rear, across both the 1998-1999 model years.
The 232 is an ANSI-standard festoon bulb, meaning it is cylindrical in form and held in place by contact pressure at each end rather than by a screw or bayonet base.
The 232 operates on a 12V, 3W electrical rating, placing it among the lower-output festoon types suited for indicator rather than illumination roles.
Its SV8.5 base designation refers to a festoon cap width of 8.5mm, a measurement that governs physical fitment within the front turn signal housing of the 748 SPS.
The 5008 is a single-filament bulb with a BA15s bayonet base, a base type characterized by a single locating pin that locks the bulb into its socket with a push-and-twist motion.
The 5008 is described as a lower wattage variant of the 1156, meaning the two share the BA15s base and are physically interchangeable in terms of socket fitment, but the 5008 draws less power.
Because the 5008 and 1156 share the same BA15s base, substituting a 1156 in the rear turn signal position of the Ducati 748 SPS would alter the wattage load on that circuit.
Both the 232 and 5008 conform to ANSI standards applicable to the US and Canadian markets, indicating these specifications reflect North American market fitment.
