Additional Notes

The 6411 is the sole bulb type listed for the Volvo V90 dome light across both available model years, 1997-1998.
The 6411 follows the ANSI standard, meaning it conforms to a specification recognized across the United States and Canada.
It is a festoon-style bulb, a form factor characterized by a cylindrical lamp body with metal end caps that make contact with spring-loaded holders on each side.
The bulb body is 36mm in length, which is the critical fitment factor for festoon bulbs, as the holder span must match this figure for proper seating.
The SV8.5 base designation refers to the end cap width of 8.5mm, a standard measurement for festoon bulbs used in interior automotive applications.
Electrical ratings are 12 volts and 5 watts, consistent with low-draw interior lighting on 12V vehicle electrical systems.
Because festoon bulbs are sized by both length and cap width, substituting a bulb that differs in either the 36mm length or the SV8.5 cap specification would result in an improper fit in the V90 dome housing.
