BMW Motorcycle F800S front and rear turn signal bulbs utilize 5008 and 232 bulb sizes, with front signals requiring both sizes and rear signals using the 5008 size. The replacement chart covers 2006 through 2008 production 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 5008 is the most frequently specified bulb across the BMW Motorcycle F800S turn signal positions, appearing in five of the six listed position-year combinations.
The 5008 operates at 12V and uses a BA15s bayonet base with a single filament. It is a lower wattage variant of the 1156 bulb, sharing the same base type but drawing less power.
The BA15s base designation indicates a single-contact bayonet fitting with a 15mm base width, which is not interchangeable with dual-contact BA15d bases used in some other automotive applications.
The rear turn signal position on the F800S uses the 5008 bulb across all three listed model years, 2006-2008.
The front turn signal position on the 2007 F800S takes a 232 bulb rather than the 5008 specified for the 2006 and 2008 model years, making the 2007 front position a notable fitment exception.
The 232 bulb is a festoon type with an SV8.5 base, rated at 12V and 3W. Its physical form and mounting style are entirely different from the BA15s bayonet base of the 5008, meaning the two bulbs are not interchangeable.
Both the 5008 and 232 are ANSI-standardized bulbs for the US and Canadian markets, meaning their specifications conform to defined industry standards rather than proprietary sizing.
All front and rear turn signal positions across the listed years carry a "Without Clear Lens" qualifier, indicating these bulb sizes apply specifically to that lens configuration.
