Additional Notes

The 12961 is a Philips miniature wedge bulb in the T10 form factor, using a W2.1x9.5d base. It operates at 12 volts with a 5-watt output, placing it in the low-intensity category typical of marker and parking light applications.
The W2.1x9.5d base designation refers to a wedge-type connection where the base width is 2.1mm and the pin spacing is 9.5mm. This base type is not compatible with bayonet or single-contact bayonet sockets, making socket type a relevant factor when sourcing a replacement.
The Polaris Slingshot S uses the 12961 bulb for the front side marker position across the 2018-2019 model years.
Because the 12961 is a Philips part number rather than an industry-standard ANSI or ECE designation, equivalent bulbs from other manufacturers must match the T10 form factor, W2.1x9.5d base, 12V rating, and 5W rating to be considered interchangeable.
