KTM 125 EXC front and rear turn signal bulbs utilize 5008 and 232 bulb sizes for illumination purposes. The replacement chart covers 1994 through 2007 model 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 two bulb types specified for the KTM 125 EXC turn signals are the 5008 and the 232, both of which conform to ANSI standards recognized in the US and Canada.
The 5008 is a single-filament bulb with a BA15s bayonet base, operating at 12 volts. It is a lower wattage variant of the widely known 1156 bulb.
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 mount by pressing between two end caps rather than inserting into a socket.
The 5008 is the more frequently specified bulb across both the front and rear turn signal positions on the KTM 125 EXC, appearing across the majority of model years from 1994 through 2007.
For the front turn signal, the 232 bulb is specified for the 1995, 2000, and 2006 model years, while the 5008 is specified for all remaining years in the 1994-2007 range.
For the rear turn signal, the 232 bulb is specified for the 1996, 1997, 1999, and 2007 model years, with the 5008 covering the remaining years.
The front and rear turn signals do not always share the same bulb type within a given model year. The 2007 model year, for instance, uses a 5008 at the front and a 232 at the rear, while 2006 reverses that arrangement.
The BA15s base of the 5008 and the SV8.5 base of the 232 are physically incompatible with each other, meaning the two bulb types are not interchangeable regardless of voltage similarity.
