Porsche Macan Trunk Bulb Size

Additional Notes

• The Porsche Macan (2020-2024) uses a 12961 bulb for the trunk position, a Philips-designated part number corresponding to the T10 miniature wedge form factor.
• The T10 designation refers to a tubular bulb approximately 10mm wide, commonly found in low-intensity interior and auxiliary lighting positions across a wide range of vehicles.
• The W2.1x9.5d base specification defines the wedge-type connection, where the bulb is held in place by friction against the socket walls rather than by a bayonet or screw mechanism.
• The 12961 operates at 12 volts and 5 watts, placing it in the low-wattage category typical of cargo area illumination, where heat output and power draw are minimal concerns.
• The W2.1x9.5d base is a standardized international designation, meaning the 12961 is not a proprietary form factor exclusive to this application.
• Because the T10 wedge base is widely standardized, aftermarket and OEM-equivalent substitutes with the same voltage, wattage, and base type are generally considered electrically compatible, though socket fit depends on physical conformity to the W2.1x9.5d specification.
