Additional Notes

The Volkswagen Touareg dome light specifications cover model years 2004-2014 and reference two distinct bulb types: the 12961 and the 6411.
The 6411 is an ANSI-standard festoon bulb, recognized across the US and Canadian markets, with a 36mm length, an SV8.5 base, and a 12V, 5W electrical rating. It is specified for the Touareg across the 2004-2010 model years.
The SV8.5 base on the 6411 is a cylindrical festoon-style fitting where the bulb makes contact at both flat ends, a common configuration in interior dome and map light applications.
The 12961 is a Philips part number designating a miniature wedge bulb in the T10 form factor, fitted with a W2.1x9.5d base. It shares the same 12V, 5W electrical rating as the 6411 and is specified for the 2011-2014 Touareg.
The W2.1x9.5d base on the 12961 is a wedge-type connector, where the glass envelope itself acts as the retaining element rather than a separate metal base, distinguishing it structurally from the festoon format of the 6411.
Despite sharing identical voltage and wattage ratings of 12V and 5W, the 12961 and 6411 use physically incompatible base types, meaning the two bulbs are not interchangeable.
The Volkswagen Touareg (2010 to 2011) represents a transition point in the dome light specifications, where the required bulb type shifts from the festoon 6411 to the wedge-based 12961.
The T10 designation on the 12961 refers to a tubular bulb with a nominal width of 10 millimeters, a standard sizing classification used across the miniature wedge bulb category.
