Additional Notes

The Toyota C-HR uses two distinct bulb types for its luggage compartment across the 2018-2022 model years: the DE3423 festoon bulb and the 168 miniature wedge bulb.
The DE3423 is a festoon-style bulb measuring 41mm in length with end-cap contacts at each end. It operates at 12V and conforms to ANSI standards applicable in the US and Canada.
The 168 is a T10 miniature wedge bulb rated at 12V and 4.9W. Its wedge base design means it is held in place by the socket itself rather than by separate contact caps, which distinguishes it physically from the DE3423.
The 2021-2022 model years specify the DE3423 festoon bulb for the luggage compartment, while the 2018-2020 model years specify the 168 wedge bulb.
The two bulb types are not interchangeable. The DE3423 uses end-cap contacts suited to a festoon socket, whereas the 168 uses a wedge base suited to a T10 socket. Substituting one for the other is not compatible with the respective socket design.
Both bulb types conform to ANSI standards for the US and Canadian markets and operate on a 12V electrical system, which is standard for automotive applications.
