The Aprilia RSV4 Factory front turn signal requires a 5008 bulb size, while rear turn signals use either 232 or 5008 bulb sizes depending on configuration. The replacement chart covers 2010 through 2015 production 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 Aprilia RSV4 Factory uses two distinct bulb types across its turn signal positions: 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 12V. 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 12V and 3W. Festoon bulbs are cylindrical in form and seat by contact pressure at each end rather than by a twist or pin-lock mechanism.
The front turn signal position on the Aprilia RSV4 Factory uses the 5008 bulb consistently across all model years from 2010-2015.
The rear turn signal position alternates between the 5008 and the 232 depending on the model year, with 2010, 2012, and 2014 using the 5008, while 2011, 2013, and 2015 use the 232.
Because the rear turn signal specification changes between model years, the 5008 and the 232 are not interchangeable in that position. The two bulbs use entirely different base types, making physical substitution incompatible without modification.
The BA15s bayonet base of the 5008 and the SV8.5 festoon base of the 232 represent fundamentally different mounting systems, which means a socket designed for one will not accept the other.
Although the front and certain rear model years share the 5008 bulb, the consistent use of the same bulb type across both positions in those years does not indicate that the sockets themselves are identical, as housing design and wiring configurations may differ by position.
