Additional Notes

The 6411 is the dome light bulb size for the Mercedes-Benz E420 across the 1994-1997 model years, with 1996 absent from the listed specifications.
The 6411 bulb follows the ANSI standard, meaning it meets the electrical and physical specifications recognized across the United States and Canada.
The 6411 is a festoon-type bulb, a cylindrical form factor that mounts by pressing its two end caps into spring clips rather than twisting or plugging into a socket.
The bulb measures 36mm in length, which is a critical fitment factor, as festoon bulbs must match the span between the fixture's retaining clips.
The SV8.5 base designation refers to the end cap width of the festoon bulb, with 8.5mm being the cap size that determines clip compatibility in the housing.
The 6411 operates at 12 volts and 5 watts, consistent with standard low-draw interior lighting in passenger vehicles of that era.
