The Husqvarna FE501 uses 232 and 5008 bulb sizes for both front and rear turn signal applications. Replacement chart data spans 2017 to 2022 model 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 Husqvarna FE501 uses two distinct bulb types across its model years for both front and rear turn signals: the 232 and the 5008, each with different base types and electrical characteristics.
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 twist-and-lock mounting mechanism common in automotive applications.
The 5008 is described as a lower wattage variant of the 1156 bulb. While it shares the same BA15s bayonet base as the 1156, the two are not electrically identical, and wattage differences may affect circuit compatibility.
Both the 232 and 5008 are ANSI-standardized bulbs for the US and Canadian markets.
On the Husqvarna FE501, the 2020-2022 model years use the 232 bulb for both front and rear turn signals, while the 2017-2019 model years use the 5008 for the same positions.
The base types of the 232 and 5008 are physically incompatible with each other. The festoon SV8.5 base and the BA15s bayonet base require different socket housings, so the two bulbs are not interchangeable.
The turn signal bulb specification is identical for both front and rear positions within any given model year, meaning the FE501 does not use different bulb types between its front and rear signal housings.
