The Vespa 946 front turn signal requires a 232 or 5008 bulb size, while the rear turn signal uses a 5008 bulb size. The replacement chart covers 2013 to 2014 model 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 Vespa 946 uses two distinct bulb types across its turn signal positions: the 232 and the 5008, both conforming to ANSI standards applicable to 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 distinguishes it from the dual-pin BA15d variant and makes the two incompatible despite their similar appearance.
The 5008 is a lower wattage variant of the 1156 bulb. While the two share the same BA15s bayonet base and are physically interchangeable in many housings, the wattage difference means substituting a 1156 for a 5008 may affect circuit load and thermal output.
On the 2014 Vespa 946, the front turn signal uses the 232 festoon bulb, while the rear turn signal uses the 5008. This means the front and rear positions require different bulb types in that model year.
On the 2013 Vespa 946, both the front and rear turn signals use the 5008 bulb, making the front and rear positions interchangeable with respect to bulb type for that year.
The front turn signal specification changed between 2013 and 2014, shifting from the 5008 to the 232. The rear turn signal retained the 5008 across both years.
