Additional Notes

The Volkswagen Eos uses the 12961 bulb for the map light across all model years from 2007-2016.
The 12961 is a Philips part number designating a miniature wedge-style bulb in the T10 form factor.
T10 refers to the bulb's tubular shape, with the number indicating a width of 10 millimeters.
The 12961 uses a W2.1x9.5d wedge base, which is a pinless base type that is held in place by the socket walls rather than by pins or a bayonet mechanism.
The bulb operates at 12 volts, consistent with standard automotive electrical systems.
At 5 watts, the 12961 is a low-wattage bulb typical of interior courtesy and reading light applications.
The T10 wedge format is one of the most widely used bulb types in automotive interior lighting, and aftermarket equivalents are commonly available under cross-reference numbers such as 194, 168, and W5W.
Fitment of the 12961 is consistent across the entire Volkswagen Eos production run, meaning no year-specific variation exists for this position.
When substituting aftermarket bulbs, the W2.1x9.5d base type must match, as physically similar T10 bulbs with differing base configurations are not interchangeable.
The 5W power rating is a fixed specification for this position; installing a higher-wattage bulb in the same socket risks exceeding the thermal tolerance of the surrounding housing.
