Additional Notes

The Toyota Matrix luggage compartment used two distinct bulb types across its production run: the DE3175 festoon bulb for 2009-2013 models and the 168 miniature wedge bulb for 2003-2008 models.
The DE3175 is a festoon-style bulb measuring 31mm in length, making contact through end-caps at each terminal rather than through a wedge base. It operates at 12V and conforms to ANSI standards applicable in both the United States and Canada.
The 168 bulb is a T10 miniature wedge type, rated at 12V and 4.9W. Its wedge base design differs fundamentally from the end-cap contact system of the DE3175, and the two types are not interchangeable.
Both bulb types carry ANSI standardization for the US and Canadian markets, meaning either type can be sourced from a wide range of manufacturers producing to that specification.
The physical mounting and contact mechanisms of the DE3175 and the 168 are incompatible with each other's sockets, so the correct bulb type must correspond to the specific model year of the vehicle.
The 4.9W power rating of the 168 bulb places it in the low-wattage range typical of interior and cargo area lighting, where heat output and current draw are kept minimal.
