Additional Notes

The Mercedes-Benz C43 AMG uses the 6411 bulb for the dome light across the 1998-2000 model years.
The 6411 is an ANSI-standardized bulb designation, meaning it conforms to a defined set of electrical and physical characteristics recognized across the US and Canadian markets.
The 6411 is a festoon-type bulb, which is a cylindrical lamp that makes contact at both ends rather than through a screw or bayonet base.
The bulb operates at 12 volts and draws 5 watts, which is consistent with low-current interior lighting applications in passenger vehicles.
The 6411 uses an SV8.5 base, a designation that refers to the contact cap style and the 8.5mm width of the end caps on a festoon bulb.
The 6411 has a 36mm length, which is a physical fitment constraint. Festoon bulbs of a different length would not seat correctly in the dome light housing of the C43 AMG.
