Additional Notes

The Saab 9-3 stepwell uses the 6411 bulb across all listed model years, spanning 2003-2011.
The 6411 is classified as a festoon bulb, meaning it is cylindrical in shape and mounts by pressing its end caps into spring clips rather than inserting into a socket.
The 6411 carries an ANSI designation, indicating it meets a standardized specification recognized in both the United States and Canada.
The bulb operates at 12 volts and 5 watts, which is consistent with low-power interior lighting applications such as stepwell illumination.
The 6411 has a 36mm length, which is a critical fitment factor, as festoon bulbs must match the span between the fixture's retaining clips.
The SV8.5 base type refers to the end cap width of the festoon bulb, and substituting a festoon bulb with a different base width risks a loose or incompatible fit within the housing.
