Additional Notes

The Toyota Tercel dome light uses the DE3175 bulb across all listed model years from 1980-1998, with 1987 absent from the specifications.
The DE3175 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.
At 31mm in length, the DE3175 fits within a spring-loaded festoon housing, where the end caps are held under tension between two contact points.
The DE3175 operates at 12 volts, consistent with the standard electrical system voltage found in passenger vehicles.
The DE3175 carries 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 interchangeable with other bulbs sharing the same 31mm length and end-cap contact configuration, provided the voltage rating is also matched.
