Additional Notes

The Toyota FJ Cruiser uses the DE3175 bulb for the trunk across all listed model years, spanning 2007-2014.
The DE3175 is 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 socket.
The DE3175 operates at 12 volts, which is consistent with standard 12V automotive electrical systems.
The 31mm length designation in the DE3175 refers to the distance between the two end-cap contacts, which is the critical fitment factor for festoon bulbs.
The DE3175 carries ANSI designation, indicating it conforms to a standardized specification recognized in both the United States and Canada.
Because festoon bulbs are held in place by spring-loaded clips that grip the end caps, the 31mm length must be matched precisely for the bulb to seat correctly in the Toyota FJ Cruiser trunk housing.
