Additional Notes

The DE3423 is a festoon-type bulb, meaning it is cylindrical in form and makes electrical contact through metal caps at both ends rather than through a base socket.
The DE3423 operates at 12 volts, which is consistent with standard automotive electrical systems.
At 41mm in length, the DE3423 must seat correctly within a fixed-length festoon holder; a bulb of a different length would either fail to make contact or would not fit the housing.
The DE3423 carries an ANSI designation, indicating it conforms to a standardized specification recognized across the United States and Canada.
The Mercedes-Benz C220 uses the DE3423 for its license plate bulb across the 1994-1996 model years.
