Additional Notes

The Saab 9-3 dome light uses the 6411 bulb size across all model years from 1999 to 2011.
The 6411 is an ANSI-standardized bulb designation, meaning it conforms to a defined set of electrical and physical specifications recognized across the United States and Canada.
The 6411 is a festoon-style bulb, a cylindrical form factor that mounts by pressing its two end caps into spring-loaded clips rather than inserting into a socket.
The bulb has a 36mm length, which is the span between its two contact ends and determines physical fitment within the dome light housing.
It uses an SV8.5 base, a designation that refers to the end-cap style specific to festoon bulbs, where 8.5 indicates the cap width in millimeters.
The 6411 operates at 12 volts, consistent with standard automotive electrical systems.
Its rated wattage is 5W, placing it in the low-power range typical of interior courtesy lighting.
Because the 6411 is an ANSI-standardized festoon bulb, other bulbs sharing the same 36mm length, SV8.5 base, 12V rating, and 5W draw are generally considered interchangeable in terms of fitment.
