Nissan Armada Trunk Bulb Size

Additional Notes

• The DE3175 is the trunk bulb size for the Nissan Armada across the 2017-2018 and 2021-2024 model years listed in these specifications.
• The DE3175 follows the ANSI standard, which is the recognized specification framework used in the United States and Canada for automotive lighting components.
• DE3175 is a festoon-type bulb, meaning it is cylindrical in shape with flat metal end-cap contacts on each end rather than a base socket or pin configuration.
• The "31" in the DE3175 designation refers to the bulb's 31mm length, which is the critical physical factor governing fitment in the trunk lamp housing.
• The bulb operates at 12 volts, consistent with the standard electrical system voltage found in passenger vehicles.
• Because festoon bulbs rely on end-cap contact pressure within a spring-loaded holder, substituting a festoon bulb of a different length, such as a 28mm or 36mm unit, would result in poor contact or no contact at all.
