Additional Notes

The DE3022 is the dominant bulb type across the Toyota Sienna luggage compartment specifications, appearing in model years 1998-2014 and 2018.
The DE3022 follows the ANSI standard recognized in the US and Canada. It is a festoon-type bulb with a 31mm length and end-cap contacts operating at 12 volts.
Festoon bulbs make contact at both ends of the cylindrical body rather than through a base socket, which is a defining characteristic of the festoon format that distinguishes it from wedge and bayonet types.
The 2023 Toyota Sienna luggage compartment uses the 12961, a Philips part number designating a T10 miniature wedge bulb with a W2.1x9.5d base, rated at 12V and 5W.
The T10 wedge format used in the 12961 relies on a plastic wedge base with wire contacts rather than end-caps, making it physically incompatible with the festoon socket used in earlier Sienna model years.
The shift from the DE3022 festoon format to the T10 wedge format in the 2023 model year reflects a socket type change, meaning the two bulb types are not interchangeable despite sharing the same 12-volt operating voltage.
