The Volvo S60 side marker utilizes a specific 12961 bulb size for illumination purposes across various production periods. Available information covers a span starting from 2001 through 2016 for the specified component.
The year-by-year compatibility chart below provides a quick reference to verify the correct bulb size for your vehicle.
The Volvo S60 front side marker position uses the 12961 bulb across the 2005-2009 model years. This is a Philips part number referencing a T10 miniature wedge bulb with a W2.1x9.5d base, rated at 12V and 5W.
The T10 wedge format of the 12961 means the bulb is held in place by friction within its socket rather than by a locking bayonet mechanism, which is a common trait of low-wattage marker and courtesy light applications.
The rear side marker position on the Volvo S60 uses the 5008 bulb for the 2001-2008 model years. The 5008 is an ANSI-standard single-filament bulb with a BA15s bayonet base, rated at 12V.
The BA15s base designation on the 5008 indicates a single-contact bayonet fitting with a 15mm base width, a format widely used in automotive signal and marker lighting.
The 5008 is described as a lower wattage variant of the 1156 bulb. Both share the BA15s bayonet base, which means the 5008 is physically interchangeable with the 1156 in terms of socket fitment, though wattage output differs between the two.
The 2009 Volvo S60 rear side marker departs from the 5008 used in prior years and instead takes the 232 bulb, a festoon type with an SV8.5 base rated at 12V and 3W. This represents a socket and bulb format change for that position in that model year.
Festoon bulbs such as the 232 are cylindrical in form and seat by spring tension between two end caps rather than inserting into a socket, making them physically incompatible with the BA15s bayonet housing used by the 5008.
The front side marker and rear side marker positions do not share the same bulb type across the S60 lineup. The front consistently uses the wedge-base 12961, while the rear uses either the bayonet-base 5008 or the festoon-base 232 depending on the model year.
A second set of rows lists the 12961 bulb for model years 2001-2009 and 2014-2016 without a sub-part label in the provided data. The 12961 specifications remain the same as those noted for the front side marker: T10 wedge, W2.1x9.5d base, 12V, 5W.
The 12961 and 232 are both rated at low wattage outputs of 5W and 3W respectively, consistent with side marker lighting requirements, which are passive visibility indicators rather than high-intensity signal sources.
