Additional Notes

The Freightliner Sprinter uses the DE3423 bulb for the interior door position across all listed model years, spanning 2010-2018.
The DE3423 is an ANSI-standardized bulb type, meaning it conforms to a defined specification recognized across the United States and Canada.
The DE3423 is a festoon-style bulb, a form factor characterized by a cylindrical body with metal end-cap contacts at each end rather than a base socket.
The bulb measures 41mm in length, which is the critical fitment factor for festoon bulbs, as the end-cap contacts must bridge the fixture's contact points at a fixed span.
The DE3423 operates at 12 volts, consistent with standard automotive electrical systems.
Because the DE3423 designation is an ANSI standard, equivalent bulbs from different manufacturers carrying the same designation share the same electrical and physical specifications, supporting interchangeability within that standard.
