The KTM 950 Supermoto uses 5008 and 232 bulb sizes for both front and rear turn signal applications. A replacement chart covering 2005 to 2008 model years documents the bulb specifications for this motorcycle.
The year-by-year compatibility chart below provides a quick reference to verify the correct bulb size for your vehicle.
The KTM 950 Supermoto uses two distinct bulb types across its turn signal positions: the 5008 and the 232, both of which conform 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 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 12V and 3W. Festoon bulbs are cylindrical in form and mount by pressing between two spring contacts rather than inserting into a socket.
The BA15s bayonet base of the 5008 features a single contact pin on the base, which distinguishes it from the dual-pin BA15d base found on some other automotive bulbs. These two base types are not interchangeable.
For the front turn signal on the KTM 950 Supermoto, the 5008 bulb is specified for the 2006-2008 model years, while the 232 is specified for 2005.
For the rear turn signal, the 5008 is specified for 2007-2008, the 232 for 2006, and the 5008 again for 2005, indicating that the front and rear positions do not always share the same bulb type within a given model year.
In the 2006 model year, the front and rear turn signals require different bulb types from each other, with the front using the 5008 and the rear using the 232. Substituting one for the other would be incorrect due to differing base designs.
In the 2005 model year, the front turn signal uses the 232 while the rear uses the 5008, again reflecting a split fitment between the two positions on the same motorcycle.
Because the 5008 and 232 use fundamentally different mounting bases, a BA15s bayonet socket and an SV8.5 festoon contact respectively, physical installation into the wrong housing is not possible without modification.
Both bulb types operate on a 12V electrical system, consistent with standard automotive and motorcycle electrical architecture.
