The Toyota Sequoia dome light utilizes 168 and DE3175 bulb sizes for the interior illumination system. Available data covers the period from 2001 through 2020 for the specified vehicle components.
The year-by-year compatibility chart below provides a quick reference to verify the correct bulb size for your vehicle.
Dome Light
If US Type and EU Type show the same value, a direct cross-reference for this bulb is not available or the data is insufficient.
The 168 bulb is an ANSI-standard miniature wedge type in the T10 form factor, rated at 12V and 4.9W. It serves as the dome light bulb for the Toyota Sequoia across the 2008-2020 model years.
The DE3175 is an ANSI-standard festoon bulb with a 31mm length and end-cap contacts, operating at 12V. It is specified for the Toyota Sequoia dome light from 2001-2007, and also appears in the rear dome light position for the 2017 and 2018 model years.
The 12961 is a Philips-numbered miniature wedge bulb in the T10 form factor with a W2.1x9.5d base, rated at 12V and 5W. It is specified for both the front and rear dome light positions on the 2021 and 2022 model years.
The 168 and 12961 bulbs share the same T10 wedge form factor but carry different wattage ratings, 4.9W and 5W respectively, and originate from different numbering systems, ANSI and Philips. These differences are relevant to fitment decisions despite their physical similarities.
The shift from the DE3175 festoon type to the 168 wedge type occurred between the 2007 and 2008 model years for the general dome light position, reflecting a change in socket design between those generations of the Sequoia.
The rear dome light on the 2017 and 2018 Sequoia uses the DE3175 festoon bulb, while the general dome light specification for those same years lists the 168 wedge bulb, indicating that different socket types are present within the same vehicle for those model years.
