Additional Notes

The Volvo 262 dome light specifications cover model years 1976 and 1978-1981, with two distinct bulb types used across that span.
The DE3423 is the more widely used bulb in these specifications, appearing in the 1976 and 1978-1980 model years.
Both the 6411 and DE3423 are festoon-type bulbs, meaning they are cylindrical in form and mount by pressing lengthwise between two contact points inside the fixture housing.
The DE3423 has a 41mm length and uses end-cap contacts, where the electrical connection is made at each flat end of the bulb.
The 6411, used in the 1981 Volvo 262, has a 36mm length and an SV8.5 base, which is a bayonet-style center-contact festoon base rather than simple end-cap contacts.
Because the 6411 and DE3423 differ in both length and base type, the two bulbs are not interchangeable despite both being festoon designs operating on 12V.
The DE3423 does not carry a listed wattage in these specifications, while the 6411 is rated at 5W.
Both bulb types conform to ANSI standards applicable to the US and Canadian markets.
The shift from the DE3423 to the 6411 occurs between the 1980 and 1981 model years, representing a change in both socket type and physical size for the dome light position.
