Additional Notes

The DE3175 is the sole dome light bulb size listed for the Nissan 810 across the 1979-1981 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 fitting into a socket, which is a common mounting arrangement in interior dome light housings.
The DE3175 has a 31mm length, which is a critical fitment factor, as festoon bulbs of differing lengths are not interchangeable even when voltage ratings match.
The bulb operates at 12 volts, consistent with the standard electrical system voltage found in passenger vehicles of that era.
End-cap contacts on the DE3175 mean electrical connection is made at both ends of the bulb, distinguishing it from bayonet or wedge-base types that use different retention and contact methods.
