Additional Notes

The DE3022 is an ANSI-standard festoon bulb with a 31mm length and end-cap contacts, operating at 12V. It serves as the luggage compartment bulb for the Toyota Prius across the 2004-2015 model years, making it the most frequently specified bulb type in this application.
The 168 is an ANSI-standard miniature wedge bulb of the T10 type, rated at 12V and 4.9W. It is the specified luggage compartment bulb for the 2016-2019 Prius.
The 12961 is a Philips part number for a miniature wedge bulb of the T10 type, using a W2.1x9.5d base and rated at 12V and 5W. It is the specified luggage compartment bulb for the 2022 Prius.
Although the 168 and the 12961 are both T10 wedge bulbs operating at 12V, they carry different part number designations and a slight wattage difference of 0.1W. The 168 follows the ANSI standard, while the 12961 is a Philips-specific designation, and the two are not listed as interchangeable across model years in these specifications.
The festoon DE3022 and the T10 wedge types use fundamentally different base designs. Festoon bulbs make contact through their end caps, while wedge bulbs are held and connected by a pinched glass base, meaning the two formats are physically incompatible with each other.
