Additional Notes

The 12961 is the most frequently specified map light bulb across the Audi S8 model years covered, appearing in the 2001, 2002, 2003, and 2007 entries.
The 12961 is a Philips part number designating a T10 miniature wedge bulb with a W2.1x9.5d base, rated at 12V and 5W.
The H6W follows the ECE standard used in Europe and worldwide markets, featuring a BAX9s base and rated at 12V and 6W.
The BAX9s base of the H6W is physically distinct from the W2.1x9.5d wedge base of the 12961, meaning the two bulb types are not interchangeable.
The 2009 Audi S8 map light takes the H6W, while all other listed model years use the 12961, reflecting a difference in socket fitment between the 2009 model and earlier ones.
The 2001-2002 and 2008 entries carry the notation "Under Central Rear View Mirror," indicating a specific mounting location for the map light in those model years.
The H6W is a single-filament signalling bulb, a construction type associated with fixed-output lighting functions rather than variable-intensity applications.
Both the H6W and the 12961 operate on a standard 12V automotive electrical system, consistent with conventional vehicle power supply requirements.
