Additional Notes

The Saturn L200 uses the 12961 bulb for the map light across the 2001-2003 model years.
The 12961 is a Philips part number designating a miniature wedge bulb in the T10 form factor with a W2.1x9.5d base.
The T10 designation refers to a tubular bulb roughly 10mm wide, a common size in automotive interior lighting applications.
The W2.1x9.5d base is a wedge-type base, meaning the bulb is held in its socket by the tension of the base itself rather than by a separate locking mechanism.
The 12961 operates at 12 volts and 5 watts, which is standard for low-current interior lighting circuits in passenger vehicles.
Because the T10 wedge base is widely shared across many vehicle makes and models, aftermarket and OEM-equivalent substitutes with the same base type and electrical rating are generally considered interchangeable with the 12961 in this application.
Substituting a bulb with a wattage higher than 5W in a socket rated for that load risks heat buildup that can damage the lens housing or socket over time.
