Additional Notes

The Toyota Sequoia luggage compartment uses three distinct bulb types across its 2001-2020 model years: the 168, 578, and DE3175, all of which conform to ANSI standards recognized in the United States and Canada.
The 578 festoon bulb is the most frequently specified type, covering the 2008-2017 model years. It operates at 12V with a 12W output and uses end-cap contacts on a 41mm-length form factor.
The DE3175 is also a festoon bulb with end-cap contacts, but its body is 31mm in length rather than 41mm. It is specified for the 2001-2007 model years and carries a 12V rating with no wattage listed in the provided data.
The 578 and DE3175 share the same festoon construction and end-cap contact design, yet their differing lengths make them non-interchangeable. Installing a 41mm bulb in a 31mm housing, or vice versa, would result in an improper fit.
The 168 is a T10 miniature wedge bulb, a fundamentally different form factor from the festoon types used in earlier model years. It operates at 12V and 4.9W and is specified for the Toyota Sequoia luggage compartment in the 2018-2020 model years.
The wedge base of the 168 bulb seats by friction into a matching socket, whereas the 578 and DE3175 festoon bulbs are held in place by spring-loaded end caps. These two contact systems are physically incompatible with each other.
At 4.9W, the 168 draws considerably less power than the 12W 578 festoon bulb used in the preceding model years, reflecting a lower wattage draw for the luggage compartment position in later production.
A fitment change from DE3175 to 578 occurred between the 2007 and 2008 model years, and a second change from 578 to 168 occurred between the 2017 and 2018 model years, meaning three separate bulb types are required to service the full 2001-2020 production range.
