Additional Notes

The Toyota Sequoia trunk uses two distinct bulb types across its model years: the DE3175 festoon bulb and the 168 miniature wedge bulb, both conforming to ANSI standards applicable in the US and Canada.
The DE3175 is a festoon-style bulb with a 31mm length and end-cap contacts, operating at 12V. Its end-cap design means it is held in place by spring-loaded clips at each end rather than a wedge socket.
The 168 is a T10 miniature wedge bulb rated at 12V and 4.9W. Its wedge base is inserted directly into a friction-fit socket, making it physically incompatible with the spring-clip holders designed for festoon bulbs.
The Toyota Sequoia uses the DE3175 festoon bulb for the 2001-2007 model years and again for the 2021 model year.
The 168 wedge bulb is specified for the 2008-2016 model years, representing a different socket type than the generations immediately before and after.
Because the DE3175 and 168 use fundamentally different mounting systems, one type cannot serve as a direct physical substitute for the other without socket modification.
Both bulb types operate on a 12V circuit, which is standard for automotive interior lighting applications.
The 2016 model year is the last in the specification to use the 168 wedge bulb, while the 2021 model year returns to the DE3175 festoon format.
