Aprilia RS 125 front and rear turn signal bulbs use 5008 and 232 sizes. The replacement chart covers 1997 to 2005 production years with bulb specifications.
The year-by-year compatibility chart below provides a quick reference to verify the correct bulb size for your vehicle.
The Aprilia RS 125 turn signal specifications span model years 1997-2005, covering both front and rear positions across nine years of production.
The 5008 is the most frequently specified bulb across both front and rear turn signal positions on the RS 125, appearing in the majority of listed model years.
The 5008 operates at 12V and uses a BA15s single-contact bayonet base. It is a single-filament bulb and is classified as a lower wattage variant of the 1156, which shares the same BA15s base type.
The 232 is a festoon bulb with an SV8.5 base, rated at 12V and 3W. Festoon bulbs are cylindrical in form and seat at both ends rather than using a bayonet or screw mount.
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 despite both being 12V units.
Both the 5008 and 232 are ANSI-standardized bulbs for the US and Canadian markets.
The front turn signal on the RS 125 uses the 232 in model years 1998, 2000, and 2001, while all other listed front turn signal years call for the 5008.
The rear turn signal on the RS 125 uses the 232 in model years 1998 and 2003, while all other listed rear turn signal years call for the 5008.
In model year 1998, both the front and rear turn signals share the 232 specification, making it the only year where a single bulb type applies to both positions simultaneously.
In several years, the front and rear turn signal positions on the RS 125 require different bulb types, so the position of the signal must be confirmed before selecting a replacement.
