Additional Notes

The DE3423 is the sole map light bulb size specified for the Mitsubishi Endeavor across all listed model years.
The DE3423 is a festoon-type bulb, meaning it is cylindrical in shape and makes electrical contact through metal caps at each end rather than through a base socket.
Festoon bulbs are held in place by spring-loaded clips that press against the end caps, a mounting method common in interior dome and map light housings.
The DE3423 has a nominal length of 41mm, which is the contact-to-contact span and determines physical fitment within the spring clip housing.
The bulb operates at 12 volts, consistent with standard automotive electrical systems.
The DE3423 conforms to ANSI standards as recognized in both the United States and Canada, indicating a standardized specification for voltage, size, and contact configuration.
The Mitsubishi Endeavor (2004-2011) uses the DE3423 for its map light, with the 41mm festoon format being a widely shared size that allows for cross-brand substitution provided the replacement meets the same length and voltage rating.
Because festoon bulbs of similar length but different designations exist, such as the 39mm DE3021 or the 44mm SV8.5 series, the 41mm specification of the DE3423 is a critical fitment factor and substitutions with differing lengths risk poor contact or failure to seat.
