Additional Notes

The Toyota Highlander luggage compartment uses two distinct bulb types across the 2008-2019 model years: the 168 and the DE3175, both of which conform to ANSI standards applicable in the United States and Canada.
The 168 bulb is a T10 miniature wedge type, operating at 12V with a rated power draw of 4.9W. Its wedge base design means it is held in place by friction against the socket walls rather than by a separate locking mechanism.
The DE3175 is a festoon-style bulb with a 31mm length and end-cap contacts. Festoon bulbs make electrical contact at both ends of the tube, which is a fundamentally different socket interface than the wedge base of the 168.
Because the 168 and DE3175 use incompatible socket types, one cannot be substituted for the other without a socket adapter or wiring modification.
The Toyota Highlander (2014-2019) uses the 168 wedge bulb for the luggage compartment.
The 2008-2013 Highlander uses the DE3175 festoon bulb in the same position, reflecting a different socket configuration in that generation.
Both bulb types operate on the standard automotive 12V electrical system, making them compatible with typical vehicle charging and battery voltage ranges.
The 2013 model year represents the transition point between the DE3175 and the 168, with 2013 using the DE3175 and 2014 adopting the 168.
