Additional Notes

The Nissan 200SX uses the DE3175 bulb size for the dome light across all model years listed in the specifications, spanning 1977-1988 and 1995-1998.
The DE3175 is a festoon-type bulb, meaning it is cylindrical in shape and makes electrical contact through metal caps at each end rather than through a base socket.
Festoon bulbs are held in place by spring-loaded clips within the dome light housing, with the end caps pressing against the contacts to complete the circuit.
The DE3175 has a nominal length of 31mm, which is a standard festoon size widely used in automotive interior lighting applications.
The bulb operates at 12 volts, consistent with the standard electrical system voltage found in passenger vehicles.
The DE3175 carries an ANSI designation, indicating it conforms to a standardized specification recognized in both the United States and Canada.
Because the DE3175 is an ANSI-standardized part, bulbs from different manufacturers carrying the same designation are generally interchangeable, provided the 31mm length and end-cap contact design are maintained.
Substituting a festoon bulb of a different length, such as a 36mm or 28mm unit, would result in improper fitment within the 200SX dome light housing due to incompatible contact spacing.
