Additional Notes

The Suzuki Motorcycle GSX-S750 uses the 12961 bulb for its parking light across the 2015-2016 and 2018-2019 model years.
The 12961 is a Philips part number designating a T10 miniature wedge bulb with a W2.1x9.5d base, rated at 12 volts and 5 watts.
The T10 designation refers to a tubular bulb with a width of 10/8 of an inch, commonly found in low-intensity automotive applications such as parking lights and instrument illumination.
The W2.1x9.5d base is a wedge-type fitting, meaning the bulb is held in place by tension from the socket rather than by a bayonet or screw mechanism.
At 5 watts, the 12961 operates as a low-power signal bulb, consistent with parking light functions that require continuous illumination without significant heat output.
The W2.1x9.5d base specification is a standardized IEC designation, and substituting a bulb with a different base type would result in an incompatible fit regardless of voltage or wattage ratings.
