Additional Notes

The Toyota T100 uses the DE3175 bulb for the trunk across all listed model years, spanning 1995-1998.
The DE3175 is a festoon-type bulb, meaning it is cylindrical in shape and seats between two spring-loaded end caps rather than fitting into a socket with a base pin or bayonet mount.
The bulb measures 31mm in length, which is a standard festoon size widely used in interior lighting applications across many vehicle makes.
It operates at 12 volts, consistent with the standard electrical system voltage found in passenger vehicles.
The DE3175 carries an ANSI designation, indicating it conforms to a standardized specification recognized in both the United States and Canada.
Because the DE3175 is an ANSI-standardized festoon bulb, it is generally interchangeable with other bulbs sharing the same 31mm length and end-cap contact configuration, provided the voltage rating matches.
