Additional Notes

The DE3175 is the sole dome light bulb size listed for the Nissan F10 across its 1976-1978 model years.
The DE3175 follows the ANSI standard, meaning it meets the electrical and physical specifications recognized across the United States and Canada.
As a festoon-type bulb, the DE3175 seats between two spring-loaded end caps rather than using a bayonet or wedge base, which is a common configuration in enclosed dome light housings.
The bulb has a 31mm length, which is the distance between its two end-cap contacts and determines whether it will seat correctly within the fixture.
The DE3175 operates at 12 volts, consistent with the standard electrical system voltage found in passenger vehicles of that era.
Because festoon bulbs are sized by their length, substituting a bulb of a different length, such as a 28mm or 36mm festoon, would result in an improper fit even if the voltage rating matches.
