Additional Notes

The Toyota Echo uses the DE3175 bulb for the dome light across its entire 2000-2005 production run, making it a single consistent specification for all model years covered.
The DE3175 is a festoon-type bulb, meaning it is cylindrical in shape with metal end caps on each side that serve as the electrical contacts, rather than a base or pin configuration.
Festoon bulbs are held in place by spring-loaded clips within the fixture that press against the end caps, so correct length is critical for proper contact and retention.
The DE3175 has a nominal length of 31mm, which is the figure that determines physical fitment in the dome light housing.
The bulb operates at 12 volts, consistent with standard automotive electrical systems.
The DE3175 designation follows ANSI standards recognized in both the United States and Canada, meaning the specification applies uniformly across North American market vehicles.
Festoon bulbs of the same length but different designations may carry different wattage or contact configurations, so cross-referencing by the DE3175 designation rather than length alone is advisable when sourcing a replacement.
