Additional Notes

The DE3175 is the sole dome light bulb size listed for the Nissan 280ZX across all documented model years, spanning 1979-1982.
The DE3175 follows the ANSI standard, meaning it conforms to a specification recognized across the United States and Canada for consistent electrical and physical characteristics.
The DE3175 is a festoon-type bulb, a form factor defined by a cylindrical body held between two end-cap contacts rather than a screw or bayonet base.
The 31mm length in the DE3175 designation is a critical fitment factor, as festoon bulbs must physically bridge the contact points within the housing, making length a primary compatibility variable.
The end-cap contact design of the DE3175 means electrical connection is made at both ends of the bulb, which is characteristic of the festoon format and distinguishes it from single-base bulb types.
The DE3175 operates at 12 volts, consistent with the standard electrical system voltage found in conventional passenger vehicles of that era.
