Additional Notes

The Toyota FJ Cruiser uses the DE3175 bulb size for its dome light across all listed model years, spanning 2007-2014.
The DE3175 is classified as 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.
The DE3175 carries an ANSI designation, indicating it conforms to a standardized specification recognized in both the United States and Canada.
The bulb operates at 12 volts, consistent with the standard electrical system voltage found in conventional passenger vehicles.
The 31mm length is a defining physical attribute of the DE3175, and festoon bulbs of differing lengths are not interchangeable, as an incorrect length will not seat properly within the dome light housing.
