Additional Notes

The Hyundai Azera uses the DE3423 bulb for its courtesy lighting across the 2006-2011 model years.
The DE3423 is a festoon-type bulb, meaning it is cylindrical in form and makes electrical contact through metal caps at each end rather than through a base socket or pins.
The DE3423 operates at 12 volts, which is consistent with standard 12-volt automotive electrical systems.
The bulb measures 41mm in length, a figure that reflects the span between the two end-cap contacts and is the primary fitment factor for festoon bulbs.
The DE3423 designation follows the ANSI standard, which applies across the United States and Canada, indicating a standardized specification recognized by both markets.
Because the DE3423 is an ANSI-standardized part, other festoon bulbs sharing the same 41mm length and 12-volt rating may be physically and electrically interchangeable, though the DE3423 designation remains the specified reference for the Azera.
