The Toyota 4Runner uses the DE3175 bulb size for the luggage compartment across the 1993-2020 model years covered in these specifications.
The DE3175 is a festoon-type bulb, meaning it is cylindrical in shape and held in place by spring-loaded end caps rather than a socket base.
Festoon bulbs make contact with the circuit through metal caps at both ends of the tube, which distinguishes them from wedge or bayonet base bulb types.
The DE3175 has a nominal length of 31mm, which is a standard festoon size widely used in interior automotive lighting applications.
The bulb operates at 12 volts, consistent with the standard electrical system voltage found in passenger vehicles and light trucks.
The DE3175 designation follows ANSI standards applicable to the United States and Canada, indicating the bulb conforms to a defined set of dimensional and electrical specifications recognized across those markets.
Because the DE3175 is an ANSI-standardized part, bulbs carrying that designation from different manufacturers are generally interchangeable as long as the 31mm festoon format and 12V rating are met.
The consistent use of a single bulb size across all listed model years of the Toyota 4Runner means a single replacement part applies to the full 1993-2020 range for this specific application.
