Additional Notes

The DE3175 is an ANSI-standardized festoon bulb used in the Nissan Murano (2003-2007) map light position. Festoon bulbs are cylindrical lamps that make electrical contact through metal caps at each end rather than through a base socket.
The 31mm figure in the DE3175 designation refers to the length of the festoon bulb, which is the critical fitment factor for this lamp type, as the end caps must span the contact points within the housing.
The 12961 is a Philips part number designating a T10 miniature wedge bulb with a W2.1x9.5d base, rated at 12V and 5W. This type uses a plastic wedge base that is held in place by friction rather than a bayonet or screw mechanism.
The Nissan Murano (2009) carries a production date qualifier of "To 10/2008," indicating that the 12961 specification applies only to vehicles produced up to that date within the 2009 model year run.
The map light bulb type changed between the 2007 and 2009-2010 model years, shifting from the festoon-style DE3175 to the wedge-style 12961. These two bulb types use different socket designs and are not interchangeable with each other.
The DE3175 and 12961 operate on the same 12V automotive electrical system, though they differ in their physical form factor and base type, which determines socket compatibility.
