Additional Notes

The T10 wedge bulb is the format used across all listed model years of the Triumph Daytona 675, appearing in the 2013-2014 and 2016-2017 license plate position.
The T10 designation refers to a tubular bulb with a 10mm body width, fitted with a W2.1x9.5d wedge base, which uses no metal pins and instead relies on two angled contact points pressed directly into the socket.
The W2.1x9.5d base type is a standardized wedge format widely used in low-current automotive lighting applications such as license plate and interior illumination.
The specified bulb operates at 12 volts and draws 5 watts, placing it in the low-wattage range typical of indicator and courtesy lighting rather than primary illumination.
The 12961 is a Philips part number assigned to this specific T10 configuration, and while the T10 form factor is broadly interchangeable across many vehicles, the 12961 designation identifies a particular product within Philips' miniature bulb range.
T10 bulbs are available from multiple manufacturers under different part numbers, but physical and electrical compatibility depends on matching the W2.1x9.5d base, 12V rating, and 5W output to the socket and circuit requirements of the Daytona 675.
