Additional Notes

The Volkswagen Tiguan map light uses two distinct bulb designations across its model years: the 2825 for 2022-2024 and the 12961 for 2009-2020.
Both the 2825 and 12961 are T10 miniature wedge bulbs sharing identical electrical ratings of 12 volts and 5 watts.
Both bulbs use the W2.1x9.5d wedge base, which is a pinless base type that is held in place by friction within the socket.
The 2825 is an ANSI-standardized designation recognized across the US and Canadian markets, while the 12961 is a Philips-assigned part number for a functionally equivalent bulb.
Because both bulbs share the same T10 form factor, W2.1x9.5d base, 12V rating, and 5W rating, they are physically and electrically interchangeable with one another.
The T10 designation refers to a tubular bulb with a width of approximately 10 millimeters, a common format in low-wattage automotive interior lighting applications.
The W2.1x9.5d base code is an IEC-defined designation where "W" indicates a wedge base, "2.1" refers to the wire contact width in millimeters, and "9.5d" refers to the base body length in millimeters.
At 5 watts on a 12-volt circuit, each bulb draws approximately 0.42 amperes, which is consistent with standard low-current interior lighting circuits found in passenger vehicles.
