Additional Notes

The DE3022 is the specified luggage compartment bulb for the Scion xB across all listed model years, spanning 2008-2015.
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.
The DE3022 has a 31mm length, which is the standard physical specification that determines fitment within the luggage compartment lamp housing.
The bulb operates at 12 volts, consistent with the standard electrical system voltage found in passenger vehicles.
The DE3022 designation follows ANSI standards recognized in both the United States and Canada, indicating a standardized specification rather than a proprietary one.
Because festoon bulbs are defined by their length and contact style, substituting a festoon bulb of a different length, such as a 28mm or 36mm unit, would result in an incorrect fit even if the voltage rating matched.
