Additional Notes

The Hyundai Genesis uses the DE3423 bulb for the license plate position across the 2009-2014 model years.
The DE3423 is classified as a festoon bulb, a cylindrical form factor that seats between two end-cap contacts rather than using a bayonet or wedge base.
Festoon bulbs are held in place by spring-loaded clips within the housing, with electrical contact made at both flat ends of the bulb.
The DE3423 has a specified length of 41mm, which is a critical fitment factor, as festoon bulbs must match the span between the contact clips in the housing to seat correctly.
The bulb operates at 12 volts, consistent with the standard electrical system voltage found in passenger vehicles.
The DE3423 designation follows ANSI standards applicable in both the United States and Canada, indicating the bulb meets a defined set of performance and dimensional criteria recognized across North America.
Festoon bulbs of differing lengths, such as the 36mm DE3175 or the 44mm DE3175 variants, are not interchangeable with the DE3423 despite sharing the same contact style, as an incorrect length will result in poor contact or failure to seat.
