Additional Notes

The Honda Motorcycle CBR600RR uses two distinct license plate bulb types across its model years, with the 168 covering 2009-2020 and the 12961 covering 2003-2008.
Both the 168 and 12961 are T10 miniature wedge bulbs, meaning they share the same physical form factor despite carrying different part designations.
The 168 is an ANSI-standardized bulb, a classification system used in the United States and Canada to define bulb specifications across manufacturers.
The 12961 is a Philips part number rather than an ANSI designation, identifying it as a manufacturer-specific reference for a T10 wedge bulb with a W2.1x9.5d base.
The W2.1x9.5d base designation on the 12961 describes a wedge-type base with a 2.1mm wire contact width and a 9.5mm insertion depth, which is the standard T10 wedge base geometry.
Both bulbs operate at 12 volts, consistent with the standard electrical system voltage found on motorcycles of this type.
The 168 is rated at 4.9 watts, while the 12961 is rated at 5 watts, placing both within the same low-wattage range typical of license plate illumination applications.
Because both bulbs share the T10 wedge form factor and nearly identical wattage ratings, the physical socket on the Honda Motorcycle CBR600RR is consistent across all listed model years.
