Additional Notes

The Acura NSX map light uses the DE3022 bulb across all listed model years from 1991 to 2001.
The DE3022 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 DE3022 has a nominal length of 31mm, which is the span between its two end contacts and determines physical fitment within the festoon holder.
The bulb operates at 12 volts, consistent with standard automotive electrical systems.
The DE3022 designation follows ANSI standards, meaning it conforms to specifications recognized across the United States and Canada.
Because the DE3022 is an ANSI-standardized part, it is interchangeable with any other bulb carrying the same designation, regardless of manufacturer, provided the voltage and physical length match.
Substituting a festoon bulb of a different length, such as a 28mm or 36mm unit, would result in either a loose fit or an inability to seat within the 31mm holder of the Acura NSX map light housing.
