Additional Notes

The Kawasaki BR125 Z125 PRO uses the 12961 bulb across the 2017-2018 and 2020 model years for its parking light position.
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 form factor approximately 10/8 of an inch wide, commonly used in low-intensity automotive lighting roles such as parking lights and marker lights.
The W2.1x9.5d base is a wedge-type base, meaning the bulb is held in its socket by the tension of the glass envelope itself rather than by a separate metal cap with pins.
At 5 watts, the 12961 operates as a low-wattage signal bulb, consistent with parking light applications that require continuous illumination without significant heat output.
The W2.1x9.5d base specification is a precise fitment standard, and substituting bulbs with physically similar but dimensionally different wedge bases risks poor socket contact or fitment failure.
