Additional Notes

The Toyota T100 uses the DE3022 bulb size for the map light across all listed model years, spanning 1993-1998.
The DE3022 is an ANSI-standardized bulb, meaning it conforms to a defined specification recognized across the United States and Canada, ensuring consistent performance and replaceability within that standard.
The DE3022 is a festoon-type bulb, a form factor characterized by a cylindrical body with metal end-cap contacts at each end rather than a base socket, allowing it to bridge two contact points within the fixture.
The bulb measures 31mm in length, which is a critical fitment factor, as festoon bulbs must physically span the fixture's contact points to make a proper electrical connection.
The DE3022 operates at 12 volts, consistent with standard automotive electrical systems.
Because festoon bulbs are available in multiple lengths, substituting a DE3022 with a festoon bulb of a different length, such as 28mm or 36mm, would result in an improper fit in the Toyota T100 map light housing.
