Additional Notes

The Mercedes-Benz C43 AMG uses the 6411 bulb for the front map light across all documented model years, covering the 1998-2000 range for both the driver side and passenger side positions.
The 6411 is a festoon-type bulb, meaning it is cylindrical in shape and mounts by pressing its end caps into spring clips rather than using a twist or plug-in socket.
The 6411 bulb follows the ANSI standard, which is the designation system used in the United States and Canada for standardized automotive and general-purpose lamps.
At 36mm in length, the 6411 fits a specific festoon housing size. Substituting a festoon bulb of a different length, such as 31mm or 41mm, would result in an improper fit within the C43 AMG map light housing.
The 6411 uses an SV8.5 base, which refers to a single-contact festoon base with an 8.5mm cap width. This base type is a defining fitment factor and must match the vehicle's socket specification.
The bulb operates at 12 volts and 5 watts, which is consistent with standard low-current interior lighting in passenger vehicles of this era.
