Additional Notes

The Toyota MR2 Spyder uses the DE3175 bulb for the map light across all listed model years, spanning 2000-2005.
The DE3175 is classified as a festoon-type bulb, meaning it is cylindrical in shape and makes electrical contact through metal caps at each end rather than through a base or pins.
The DE3175 operates at 12 volts, which is consistent with standard automotive electrical systems.
The festoon format of the DE3175 requires a holder that accepts end-cap contacts, so pin-base or wedge-base bulbs are not interchangeable with this fitment.
The DE3175 designation follows ANSI standards recognized in both the United States and Canada, placing it within a standardized North American bulb classification system.
The 31mm length is a defining physical attribute of the DE3175, and festoon bulbs of differing lengths, such as the DE3021 at 28mm or the DE41 at 41mm, are not compatible with this application.
