Additional Notes

The Nissan Frontier (1998-2019) uses the DE3175 bulb size for the dome light across all listed model years.
The DE3175 is a festoon-style 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 automotive electrical systems.
The 31mm length designation in the DE3175 specification refers to the physical span between the two end caps, which must match the holder spacing in the vehicle's dome light housing.
The DE3175 carries an ANSI standard classification, indicating it meets a defined technical specification recognized across the United States and Canada.
Because the DE3175 is an ANSI-standardized festoon bulb, replacement units from multiple manufacturers are generally interchangeable as long as the 31mm length and 12V rating are maintained.
The end-cap contact design of festoon bulbs differs from wedge-base or bayonet-base bulbs, making those types incompatible with a holder designed for the DE3175.
