Additional Notes

The Honda Odyssey trunk bulb specifications cover two distinct generations, with the 1995-1998 models using the DE3022 and the 2021-2024 models using the 12961.
The 12961 is a Philips part number designation for a T10 miniature wedge bulb rated at 12V and 5W, fitted with a W2.1x9.5d base.
The T10 wedge base design means the bulb is held in its socket by the tension of the base contacts rather than by a bayonet or screw mechanism.
The DE3022 is an ANSI-standardized festoon bulb recognized across the US and Canadian markets, operating at 12V with a 31mm length and end-cap contacts.
Festoon bulbs make electrical contact at both ends of the bulb body, which is a fundamentally different contact arrangement than the wedge base used by the 12961.
The two bulb types are not interchangeable, as the wedge socket used for the 12961 and the festoon socket used for the DE3022 are physically incompatible with each other.
The W2.1x9.5d base designation on the 12961 refers to a standardized IEC base code, where 2.1 indicates the contact wire width and 9.5d describes the base body dimensions.
The DE3022 follows ANSI standardization, meaning bulbs from multiple manufacturers conforming to that standard are considered direct replacements for one another.
