BMW Motorcycle F800ST front and rear turn signal bulbs utilize 232 and 5008 bulb sizes. The replacement chart covers vehicle production spanning 2006 to 2012.
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 across all model years of the BMW Motorcycle F800ST turn signals are the 232 and the 5008, both of which conform 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 make contact at both ends rather than through a base 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 determines rotational orientation during installation.
The 5008 is a lower wattage variant of the 1156 bulb. While both share the BA15s bayonet base, the wattage difference means the two are not electrically equivalent and are not interchangeable without affecting circuit load.
The front turn signal on the F800ST used the 5008 for model years 2006-2010, then transitioned to the 232 for 2011-2012. These two bulbs use physically different base types, making them non-interchangeable.
The rear turn signal specification for the F800ST shows variation across its production run. The 5008 was specified for 2006 and 2008-2011, while the 232 was specified for 2007 and 2012, indicating that front and rear positions did not always share the same bulb type within a given model year.
In model year 2012, the F800ST front and rear turn signals both use the 232 bulb, making it the only year in the specifications where both positions share the same bulb type.
In model year 2007, the front turn signal uses the 5008 while the rear uses the 232, meaning the two positions require different bulb types despite both being turn signal applications on the same vehicle.
All entries across both front and rear turn signal positions carry the qualifier "Without Clear Lens," indicating these bulb sizes apply specifically to that lens configuration.
