The Ducati MH900e turn signal bulb utilizes 5008 and 232 sizes for both front and rear positions. Replacement specifications in the chart cover 2000 to 2002 production years.
The year-by-year compatibility chart below provides a quick reference to verify the correct bulb size for your vehicle.
The Ducati MH900e uses two distinct bulb types across its front and rear turn signal positions: the 5008 and the 232, both conforming to ANSI standards applicable in the US and Canada.
The 5008 is a single-filament bulb with a BA15s bayonet base, operating at 12V. It is a lower wattage variant of the 1156 bulb, sharing the same base type but drawing less power.
The 232 is a festoon bulb with an SV8.5 base, rated at 12V and 3W. Festoon bulbs are cylindrical in form and seat by contact pressure at each end rather than by a twist or push-in base.
The BA15s bayonet base of the 5008 is a single-contact design, meaning it is not interchangeable with dual-contact bayonet bulbs such as the BA15d, despite sharing a physically similar housing.
For the 2001 Ducati MH900e, both the front and rear turn signals use the 5008 bulb, making the fitment uniform across all four positions that year.
In the 2002 model year, the front turn signal uses the 5008 while the rear uses the 232, meaning the two positions require different bulb types and are not interchangeable with each other.
In the 2000 model year, the front turn signal uses the 232 and the rear uses the 5008, a configuration that is the reverse of the 2002 arrangement.
Because the 5008 and 232 use fundamentally different base types, a bayonet base and a festoon contact base respectively, substituting one for the other in any position is not physically possible without modification.
