The Aprilia RS 250 front and rear turn signal bulbs utilize 232 and 5008 bulb sizes according to specifications. The replacement chart covers 1996 to 2002 production years with corresponding bulb size data.
The year-by-year compatibility chart below provides a quick reference to verify the correct bulb size for your vehicle.
The Aprilia RS 250 front and rear turn signals draw from two bulb types across the 1996-2002 model range: the 232 and the 5008, both of which conform to ANSI standards recognized in the United States 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 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 contact pressure at each end rather than by a pin or bayonet mechanism.
The BA15s bayonet base of the 5008 features a single locating pin, which distinguishes it from the dual-pin BA15d base. Substituting a dual-pin base bulb into a single-pin socket is not mechanically compatible.
For the Aprilia RS 250, the front turn signal on the 1998 and 2002 models uses the 232 festoon bulb, while all other listed model years use the 5008.
The rear turn signal on the 1998 model also uses the 232, whereas all other listed model years for the rear position use the 5008.
The 1999-2001 model years use the 5008 in both the front and rear turn signal positions, making the same bulb type applicable to all four turn signal housings on those vehicles.
Because the 232 and 5008 differ in both base type and physical form, they are not interchangeable with each other regardless of voltage compatibility.
