Volkswagen EuroVan Map Light Bulb Size

Additional Notes

• The Volkswagen EuroVan uses the 12961 bulb across all listed model years for the map light position.
• The 12961 is a Philips part number designating a miniature wedge bulb in the T10 form factor with a W2.1x9.5d base.
• The T10 designation refers to a tubular bulb approximately 10mm wide, commonly found in low-intensity interior lighting applications such as map, dome, and courtesy lights.
• The W2.1x9.5d base is a wedge-type base, meaning the bulb is held in its socket by the tension of the glass envelope itself rather than by a separate metal cap or bayonet fitting.
• The 12961 operates at 12 volts and 5 watts, which is consistent with standard automotive interior lighting circuits.
• The listed model years span 1993-2003, with the same 12961 specification applying uniformly across that range for the map light.
• Because the W2.1x9.5d base is a specific wedge standard, substitution with other wedge bulbs carrying different base codes risks an improper fit even if the physical size appears similar.
• The T10 wedge format is widely produced by multiple manufacturers, though the 12961 designation is specific to Philips and may carry different part numbers under other brands while retaining the same electrical and base specifications.
