BMW Motorcycle F650GS front and rear turn signal bulbs use 5008 and 232 size specifications. The replacement chart covers 2001 through 2012 production years with corresponding bulb size data.
The year-by-year compatibility chart below provides a quick reference to verify the correct bulb size for your vehicle.
The BMW Motorcycle F650GS turn signal specifications reference two bulb types across its model years: the 5008 and the 232, both of which are ANSI-standard bulbs rated for 12-volt systems and recognized in the US and Canadian markets.
The 5008 is a single-filament bulb with a BA15s bayonet base and is described as a lower wattage variant of the more widely known 1156 bulb type.
The 232 is a festoon bulb with an SV8.5 base, rated at 12V and 3W. Festoon bulbs are cylindrical in form and mount by pressing between two end caps rather than inserting into a socket, which makes them physically distinct from the bayonet-style 5008.
The 5008 is the more frequently specified bulb across both front and rear turn signal positions throughout the F650GS model range from 2001-2012.
The 232 and 5008 use fundamentally different base types, a festoon cap versus a bayonet socket, meaning the two bulbs are not interchangeable despite both being 12-volt single-filament light sources.
For the front turn signal on the BMW Motorcycle F650GS, the 2008-2010 model years specify the 5008 with a "Without Clear Lens" qualifier, while the 2009 model year specifies the 232 under the same qualifier, indicating that lens type is a relevant factor in bulb selection for this position.
The rear turn signal position shows a divergence in 2008 and 2009, where the 2008 model year specifies the 5008 and the 2009 model year specifies the 232, both noted as "Without Clear Lens," meaning the same model year's front and rear positions do not always share the same bulb type.
In 2004, both the front and rear turn signal positions specify the 232 bulb, making it one of the few model years where both positions share the same bulb type rather than the more common 5008.
The "Without Clear Lens" qualifier present on 2008-2012 entries for one or both turn signal positions suggests that lens configuration is a fitment variable that affects which bulb size applies, and the specifications do not cover a "With Clear Lens" variant for those years.
The 2006 rear turn signal specifies the 232, while the 2006 front turn signal specifies the 5008, meaning front and rear positions on the same model year can require different bulb types and base styles.
