Additional Notes

The Nissan B210 uses the DE3175 bulb across all listed model years, spanning 1973-1978.
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.
The 31mm length in the DE3175 designation refers to the distance between the two end caps, which is the critical fitment factor for festoon bulbs in dome light housings.
The DE3175 operates at 12 volts, consistent with the standard electrical system voltage found in passenger vehicles of this era.
The DE3175 carries ANSI standardization, meaning it conforms to a defined specification recognized across the United States and Canada.
Because festoon bulbs are held under spring tension between two contact points, the 31mm length must be matched precisely for the bulb to seat correctly and maintain a reliable circuit.
The consistent use of a single bulb type across the entire 1973-1978 production span of the Nissan B210 indicates no dome light housing changes that would affect bulb fitment during those years.
