Additional Notes

The DE3175 is the dome light bulb size for the Lexus ES250 across both available model years, 1990-1991.
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.
The bulb operates at 12 volts, consistent with standard automotive electrical systems.
The DE3175 designation follows ANSI standards, indicating the specification is recognized across the United States and Canada.
The festoon bulb measures 31mm in length, which is the critical fitment factor for the dome light housing in this application.
