Additional Notes

The Toyota Supra uses the DE3022 bulb for trunk illumination across all listed model years from 1986-1998.
The DE3022 is a festoon-type bulb, meaning it is cylindrical in form and makes electrical contact through metal caps at each end rather than through a base socket.
Festoon bulbs are held in place by spring-loaded clips that press against the end caps, a mounting method common in enclosed interior lighting applications such as trunk compartments.
The DE3022 has a nominal length of 31mm, which is a standard festoon size also referenced in some applications as the "31mm festoon" category.
The bulb operates on a 12V circuit, consistent with the standard electrical system voltage found in passenger vehicles.
The DE3022 designation follows ANSI standards applicable in the United States and Canada, indicating the bulb conforms to defined performance and dimensional criteria within those markets.
When replacing the trunk bulb in the Toyota Supra (1986-1998), the 31mm end-cap festoon format is a fitment requirement, as festoon bulbs of differing lengths are not interchangeable within the same housing.
