Additional Notes

The KTM 450 EXC-R uses the 12961 bulb for the license plate position across the 2008-2011 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 form factor approximately 10mm wide, commonly found in low-current auxiliary lighting positions such as license plate lamps.
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 draws minimal current, which is typical for a license plate lamp that operates continuously alongside other vehicle lighting circuits.
The consistent use of the same bulb number across all four model years indicates that the license plate lamp housing and socket specification remained unchanged throughout this production period.
When sourcing a replacement, the W2.1x9.5d base type must match exactly, as wedge bulbs with differing base widths or pin spacing are not interchangeable even if the wattage rating is the same.
