BMW Motorcycle F650 front turn signal bulbs use 5008 size, while rear turn signal bulbs use 232 or 5008 size specifications. The replacement chart covers 1997 to 2000 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 F650 uses two bulb types across its turn signal positions: the 5008 and the 232, both conforming to ANSI standards applicable in the US and Canada.
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 bulb with an SV8.5 base, rated at 12V and 3W. Festoon bulbs are cylindrical in form and seat at both ends rather than using a traditional base socket.
The front turn signal position on the F650 uses the 5008 bulb consistently across the 1997-2000 model years.
The rear turn signal position does not follow a consistent pattern across the same model years. The 1997 and 1999 models use the 5008, while the 1998 and 2000 models use the 232.
The BA15s bayonet base of the 5008 and the SV8.5 festoon base of the 232 are physically incompatible with each other, meaning the two bulb types are not interchangeable regardless of shared voltage rating.
When servicing the rear turn signal on the F650, the correct bulb type varies by model year, and substituting one type for the other would result in an improper fit.
