BMW Motorcycle F800GS front and rear turn signal bulbs use 5008 and 232 size specifications. The replacement chart covers 2008 to 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 F800GS uses two distinct bulb types across its front and rear turn signal positions: the 5008 and the 232, both of which are ANSI-standard bulbs rated for the US and Canadian markets.
The 5008 is a single-filament bulb with a BA15s bayonet base, operating at 12V. It is a lower wattage variant of the more widely known 1156 bulb.
The 232 is a festoon-style bulb with an SV8.5 base, rated at 12V and 3W. Its festoon form factor differs structurally from the 5008, as it seats by compression between two end caps rather than by a bayonet mount.
The 5008 and 232 are not interchangeable. Their base types are physically incompatible, and substituting one for the other in a given socket is not possible without modification.
All turn signal positions across all listed model years carry the qualifier "Without Clear Lens," indicating the bulb size applies specifically to that lens configuration.
For the front turn signal, the F800GS uses the 5008 in 2008-2009 and 2011-2012, while the 2010 model year uses the 232 instead.
For the rear turn signal, the 5008 is specified for 2008-2009 and 2011-2012. The 2010 model year again uses the 232, consistent with its front turn signal fitment that year.
The 2010 F800GS is the only model year in the listed specifications where both the front and rear turn signals share the 232 festoon bulb rather than the 5008.
