The Audi SQ5 side marker utilizes a specific 12961 bulb size for illumination purposes within the lighting assembly. Data for the specified component covers the period from 2017 through 2024.
The year-by-year compatibility chart below provides a quick reference to verify the correct bulb size for your vehicle.
The 12961 is a Philips part number designating a miniature wedge bulb in the T10 form factor, fitted with a W2.1x9.5d base and rated at 12 volts and 5 watts.
The T10 wedge base design means the bulb is held in place by the tension of the socket itself rather than by a bayonet or screw mechanism, which is a common trait of low-wattage marker and courtesy lighting applications.
The Audi SQ5 uses the 12961 bulb across its rear side marker positions for the 2017-2024 model years.
The 2017 fitment carries a VIN restriction, applying only from VIN FY-H-000 001 onward, indicating a mid-production specification change for that model year.
The 2020 model year specifies the 12961 for the bumper position, distinguishing it as a location-specific fitment rather than a general rear side marker application.
The 2019 model year notes a lower body position alongside a reference to LED rear combination lamp and increased safety requirements, indicating that the 12961 in that year coexists with an LED rear lighting assembly rather than replacing it.
At 5 watts, the 12961 operates at a low power draw consistent with side marker and parking light functions, where continuous illumination without significant heat generation is a design priority.
The W2.1x9.5d base is a standardized IEC designation, meaning the 12961 is interchangeable with other T10 wedge bulbs sharing that base specification, provided voltage and wattage ratings are also matched.
