Additional Notes

The Aston Martin V8 Vantage uses the 12821 bulb for its license plate position across the 2006-2017 model years.
The 12821 is a Philips part number designating a miniature wedge bulb in the T10 form factor, which is one of the most widely used bulb types in automotive exterior lighting applications.
The T10 designation refers to the bulb's tubular shape, with the number indicating its width in tenths of an inch, making it a compact unit suited to low-profile housings such as license plate assemblies.
The 12821 operates at 12 volts and 5 watts, a standard low-wattage rating consistent with illumination tasks that require visibility without significant heat output or power draw.
The base type is W2.1x9.5d, a wedge-style base that relies on tension from the socket rather than a bayonet or screw mechanism to maintain contact, which is a common fitment method in license plate and interior bulb positions.
The W2.1x9.5d base specification is a precise fitment detail; substituting a bulb with a physically similar but dimensionally different base risks poor contact or socket damage.
Because the same bulb size applies uniformly across all twelve listed model years of the V8 Vantage, no year-specific fitment variation exists within this range for the license plate position.
The T10 wedge format is shared across many vehicle makes and models, meaning the 12821 is not exclusive to this application, though compatibility must still be confirmed against voltage and wattage requirements before substitution.
