Additional Notes

The DE3175 is the trunk bulb size across all listed model years of the Infiniti QX80, spanning 2014-2024.
The DE3175 follows the ANSI standard, which is the recognized specification framework used in the United States and Canada for automotive lighting components.
As a festoon-type bulb, the DE3175 is cylindrical in form and seats between two end-cap contacts rather than using a plug-in base, which is a defining characteristic of the festoon format.
The DE3175 has a 31mm length, which is the figure that distinguishes it from other festoon bulbs such as the DE3021 (28mm) or the DE41 (41mm), making length a critical factor in fitment.
The bulb operates at 12 volts, consistent with the standard electrical system voltage found in passenger vehicles.
Because festoon bulbs of similar length but different end-cap configurations exist in the market, substitutions should be verified against the 31mm length and end-cap contact type specific to the DE3175.
