The Husqvarna FE450 uses 232 and 5008 bulb sizes for both front and rear turn signal applications. A replacement chart covering 2015 through 2021 model years documents the bulb size specifications for this motorcycle.
The year-by-year compatibility chart below provides a quick reference to verify the correct bulb size for your vehicle.
The two bulb types specified for the Husqvarna FE450 turn signals are the 232 and the 5008, both of which conform to ANSI standards recognized in the US and Canada.
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, rated at 12V. The BA15s base uses a single locating pin, which orients the bulb in one position during installation.
The 5008 is described as a lower wattage variant of the 1156. While the two share the same BA15s bayonet base, they are not the same bulb, and the wattage difference is a relevant factor in turn signal circuit compatibility.
The Husqvarna FE450 used the 5008 bulb in both the front and rear turn signals across the 2015-2019 model years.
For the 2020-2021 model years, both the front and rear turn signals on the FE450 use the 232 festoon bulb rather than the 5008.
The bulb type change between the 2019 and 2020 model years affects both signal positions simultaneously, meaning the front and rear housings are not interchangeable across that model year boundary.
Because the 232 and 5008 use entirely different base types, one cannot be substituted for the other regardless of voltage compatibility.
