Additional Notes

The Suzuki Motorcycle GW250 uses the 12961 bulb for its license plate light across the 2013-2017 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 form factor is a small tubular bulb type widely used in low-intensity automotive lighting positions such as license plate, courtesy, and side marker applications.
The W2.1x9.5d base designation refers to a wedge-style base with a 2.1 mm wire contact width and a 9.5 mm insertion depth, which seats by friction rather than by a bayonet or screw mechanism.
At 5 watts, the bulb draws minimal current, consistent with its role as an auxiliary lighting component rather than a primary illumination source.
Because the 12961 is a manufacturer-specific part number from Philips, equivalent bulbs from other manufacturers are cross-referenced by their shared T10 / W5W specification rather than by this number alone, and fitment should be confirmed against the W2.1x9.5d base type.
