BMW Motorcycle F650CS front and rear turn signal bulbs utilize a 232 and 5008 size. The replacement chart covers 2001 to 2006 production specifications.
The year-by-year compatibility chart below provides a quick reference to verify the correct bulb size for your vehicle.
The BMW Motorcycle F650CS uses two distinct bulb types across its turn signal positions: the 232 and the 5008, both of which conform to ANSI standards for the US and Canadian markets.
The 232 is a festoon-style bulb with an SV8.5 base, rated at 12V and 3W. Its festoon form factor means it is held in place by contact at each end rather than by a socket base.
The 5008 is a single-filament bulb with a BA15s bayonet base, rated at 12V. It is a lower wattage variant of the 1156 bulb, sharing the same base type but drawing less power.
Because the 232 and 5008 use fundamentally different base types, an SV8.5 festoon socket and a BA15s bayonet socket are not interchangeable, and substituting one bulb for the other in a given position is not physically compatible.
For the front turn signal on the F650CS, the 232 bulb applies to the 2002-2004 and 2006 model years, while the 5008 applies to 2001 and 2005.
For the rear turn signal, the 232 bulb applies to the 2004-2006 model years, while the 5008 applies to 2001-2003.
The 2005 F650CS presents an opposing configuration between its front and rear turn signals: the front position uses the 5008 while the rear uses the 232.
The 2003 model year similarly shows a split configuration, with the front position using the 232 and the rear using the 5008.
The 232 bulb is the more prevalent type across the full set of specifications, appearing in a greater number of position-and-year combinations than the 5008.
The 2006 model year is the only one in which both the front and rear turn signal positions share the same bulb type, with the 232 specified for both.
