Additional Notes

The 6411 bulb is the map light specification for the Mercedes-Benz C55 AMG across the 2005-2006 model years.
The 6411 follows the ANSI standard, which is the American National Standards Institute classification system used to define bulb specifications for the US and Canadian markets.
It is a festoon-type bulb, meaning it is cylindrical in shape with metal end caps that make contact with spring-loaded holders on both ends of the housing.
The bulb measures 36mm in length, which is a critical fitment factor, as festoon bulbs must match the span of the socket to seat correctly.
The SV8.5 base designation refers to the cap style used on this festoon bulb, where the 8.5 indicates the cap width in millimeters.
The 6411 operates at 12 volts and 5 watts, consistent with standard low-draw interior lighting in passenger vehicles of this era.
