The Ducati 748S Monoposto uses 5008 and 232 bulb sizes for both front and rear turn signal applications. The replacement chart covers 2000 to 2002 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 748S Monoposto uses two distinct bulb types across its front and rear turn signal positions: the 5008 and the 232, both of which are ANSI-standardized bulbs for the US and Canadian markets.
The 5008 is a single-filament bulb with a BA15s bayonet base, operating at 12 volts. It is a lower wattage variant of the more widely known 1156 bulb, sharing the same base type but drawing less power.
The 232 is a festoon-style bulb with an SV8.5 base, rated at 12 volts and 3 watts. Festoon bulbs are cylindrical in form and seat by pressing between two end caps rather than inserting into a socket with a base pin or bayonet mount.
The BA15s bayonet base of the 5008 features a single contact pin on its base, distinguishing it from dual-pin bayonet variants such as the BA15d. This single-pin configuration is consistent with single-filament operation.
For the 2001 Ducati 748S Monoposto, the front turn signal takes a 232 festoon bulb while the rear takes a 5008 bayonet bulb, meaning the front and rear positions use different bulb types in that model year.
For the 2000 model year, the front turn signal uses a 5008 and the rear uses a 232, which is the reverse of the 2001 front-to-rear arrangement.
In the 2002 model year, both the front and rear turn signal positions use the 5008 bulb, making it the only year in the listed specifications where both positions share the same bulb type.
The 5008 and 232 are not interchangeable. Their base types, physical forms, and mounting methods are fundamentally different, and substituting one for the other in a given socket is not possible without modification.
