Additional Notes

The Toyota Previa uses the DE3175 bulb for the dome light across all listed model years, spanning 1991-1997.
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 DE3175 operates at 12 volts, which is consistent with standard automotive electrical systems.
The 31mm length designation in the DE3175 specification refers to the physical span between the two end-cap contacts, a critical factor in fitment within the dome light housing.
The DE3175 carries ANSI standardization for the United States and Canada, indicating the bulb conforms to a defined set of performance and construction criteria recognized across those markets.
Because the DE3175 specification remains unchanged across the entire 1991-1997 production run of the Toyota Previa, bulbs sourced for any listed year are interchangeable with those for any other listed year in this range.
