Additional Notes

The Nissan TITAN map light draws from two distinct bulb types across its model years: the DE3175 festoon bulb and the 168 miniature wedge bulb.
The DE3175 is a festoon-style bulb measuring 31mm in length with end-cap contacts, operating at 12V. Its cylindrical form factor seats between two spring-clip holders rather than inserting into a socket.
The 168 is a T10 miniature wedge bulb rated at 12V and 4.9W. The wedge base is formed by the glass envelope itself, which is pinched at the bottom to create a friction fit within the socket.
Both bulb types conform to ANSI standards applicable in the United States and Canada.
The DE3175 and the 168 are not interchangeable. Their base types differ fundamentally, as one uses end-cap contacts and the other uses a wedge base, making them physically incompatible with the same socket.
The Nissan TITAN (2004-2008) uses the DE3175 for the map light, followed by a transition to the 168 bulb beginning in 2009.
The 168 wedge bulb is specified for model years 2009-2015.
The DE3175 returns as the specified map light bulb for the 2017-2019 Nissan TITAN, coinciding with the second-generation body style introduced for that era.
