Additional Notes

The DE3423 is a festoon-type bulb, meaning it is cylindrical in shape with flat metal contacts at each end rather than a screw or bayonet base. It operates at 12 volts and measures 41mm in length, which is the standard fitting length for this application.
The DE3423 designation follows the ANSI standard used in the United States and Canada, making it a regionally standardized part rather than a proprietary specification.
The INFINITI QX60 uses the DE3423 for the trunk bulb position across the 2023-2024 model years.
Festoon bulbs of the same voltage but different lengths are not interchangeable. A bulb shorter or longer than 41mm will not seat correctly in the festoon holder, as the end-cap contacts must span the exact distance between the holder's terminals.
