Additional Notes

The Toyota Supra uses the DE3022 bulb size for courtesy lighting across the 1986-1993 model years.
The DE3022 is a festoon-type bulb, meaning it is cylindrical in shape with metal end caps that serve as its electrical contacts rather than a base pin or wedge fitting.
Festoon bulbs are held in place by spring-loaded clips within the socket, which grip the end caps at both sides of the bulb body.
The DE3022 has a nominal length of 31mm, which is a standard festoon size shared with several other bulb designations, making physical fitment possible across multiple part numbers of the same length.
The DE3022 operates at 12 volts, consistent with the standard electrical system voltage found in passenger vehicles of this era.
The DE3022 carries an ANSI designation, indicating it conforms to a standardized specification recognized in the United States and Canada, which governs its electrical and physical characteristics.
Because multiple festoon bulb part numbers share the 31mm length, substitution with a physically compatible bulb of a different designation is possible only when the voltage and wattage ratings also match those of the DE3022.
