Aprilia Rally 50 (Air Cooled) Turn Signal Bulb Size
The Aprilia Rally 50 (Air Cooled) front and rear turn signal bulbs utilize a 232 or 5008 size. The replacement chart covers 1995 to 2004 production years with corresponding bulb specifications.
The year-by-year compatibility chart below provides a quick reference to verify the correct bulb size for your vehicle.
The Aprilia Rally 50 (Air Cooled) uses two bulb types across its turn signal positions: the 232 and the 5008, both of which are ANSI-standardized for the US and Canadian markets.
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 their end caps into spring clips rather than inserting into a socket.
The 5008 is a single-filament bulb with a BA15s bayonet base, operating at 12V. The BA15s base uses a single locating pin, which means it is not interchangeable with dual-pin bayonet variants such as the BA15d.
The 5008 is described as a lower wattage variant of the 1156. While the two share the same BA15s bayonet base, their wattage ratings differ, and substituting one for the other may affect turn signal flash rates or circuit load.
Front and rear turn signal positions do not always share the same bulb type within a given model year, which means the two positions require separate verification before replacement.
In the 2004 model year, both the front and rear turn signals use the 232 bulb, making it the only year where both positions share the same specification.
For the front turn signal, the 5008 was specified across 1995-2003, with the exception of 1997 and 2004, both of which use the 232.
For the rear turn signal, the 5008 was specified for 1995-1998 and 2003, while the 232 was specified for 1999-2002 and 2004.
The 1997 model year presents a split fitment, with the front turn signal using the 232 and the rear using the 5008, which are physically and electrically distinct bulb types.
Because the 232 and 5008 differ in both base type and wattage, they are not interchangeable, and installing the incorrect type in either position would require a base adapter or circuit adjustment to function properly.
