Additional Notes

The Nissan Sentra map light uses three distinct bulb types across the 2000-2012 model years: the 168, the 68, and the DE3175.
The 168 bulb is a T10 miniature wedge type rated at 12V and 4.9W, and it fits the Nissan Sentra map light position for the 2007-2012 model years.
The wedge base of the 168 bulb means it is held in place by friction rather than a locking mechanism, which distinguishes it from bayonet-style bulbs.
The 68 bulb carries a BA15s single-contact bayonet base and is rated at 12V and 6W, making it slightly higher in wattage than the 168.
The BA15s base of the 68 bulb requires a twist-and-lock installation, and this type is not interchangeable with wedge or festoon sockets without an adapter.
The 68 bulb applies to the Nissan Sentra map light for the 2004-2006 model years.
The DE3175 is a festoon-style bulb measuring 31mm in length, making contact through metal end caps rather than a base socket.
The DE3175 is the specified map light bulb for the Nissan Sentra across the 2000-2003 model years.
All three bulb types in these specifications conform to ANSI standards applicable in both the United States and Canada.
Because the 168, 68, and DE3175 each use a different base type, they are not directly interchangeable with one another without modification to the socket housing.
