Additional Notes

The Volvo 244 dome light specifications span model years 1975 through 1989, with three distinct bulb types used across that range: the 6411, DE3423, and 212-2.
The 6411 is the most frequently specified bulb in the Volvo 244 dome light fitment, covering model years 1981-1989.
The 6411 is an ANSI-standard festoon bulb rated at 12V and 5W, with a 36mm length and an SV8.5 base.
The DE3423 is an ANSI-standard festoon bulb with a 41mm length, rated at 12V, and uses end-cap contacts rather than an SV8.5 base. It is specified for the Volvo 244 in model years 1975-1977 and 1980.
The 212-2 is an ANSI-standard festoon bulb with a 41mm length and an SV8.5 base, rated at 12V and 12W. It is specified for model years 1978-1979.
Although the DE3423 and 212-2 share the same 41mm length, their base types differ. The DE3423 uses end-cap contacts while the 212-2 uses an SV8.5 base, making them non-interchangeable in sockets designed for one contact type specifically.
The 6411 at 36mm is physically shorter than both the DE3423 and 212-2 at 41mm, which means the 6411 is not a direct length-compatible substitute for either of the other two bulb types.
The wattage difference between the 6411 (5W) and the 212-2 (12W) is significant. Substituting one for the other in a socket not designed for the replacement could affect circuit load and light output.
The SV8.5 base designation on both the 6411 and 212-2 refers to a festoon base with a nominal 8.5mm cap width, a common standard that allows those two bulbs to fit the same socket type, though their differing lengths and wattages still affect direct interchangeability.
All three bulb types carry ANSI standard status applicable to the US and Canadian markets, indicating they conform to standardized electrical and physical specifications within those regions.
