Additional Notes

The 12961 is a miniature wedge bulb in the T10 form factor, using a W2.1x9.5d base. This base type features two contact points on a 9.5mm-wide plastic wedge, which allows the bulb to be inserted directly into a socket without a separate metal connector.
The 12961 operates at 12 volts and draws 5 watts, which is standard for low-current license plate lighting applications in 12-volt automotive electrical systems.
The Saturn L100 uses the 12961 bulb for the license plate position across the 2001-2002 model years.
The 12961 is a Philips part number. The same T10 W2.1x9.5d specification is shared across many manufacturer part numbers, meaning physical and electrical equivalents from other suppliers are generally interchangeable provided they match the 12V, 5W rating and W2.1x9.5d base.
