Additional Notes

The Mercedes-Benz C280 uses the 6411 bulb size across all listed model years for its map light positions.
The 6411 is an ANSI-standardized bulb designation recognized in both the United States and Canada, meaning it conforms to a defined set of electrical and physical specifications shared across manufacturers.
The 6411 is a festoon-style bulb, which means it is cylindrical in shape and mounts by pressing its two end caps into spring-loaded clips rather than inserting into a socket.
The 6411 bulb has a length of 36mm, which is a critical fitment factor, as festoon bulbs must match the span between the fixture's retaining clips to seat correctly.
It uses an SV8.5 base, a designation that refers to the end cap width of 8.5mm, which must correspond to the fixture's clip width for proper retention.
The bulb operates at 12 volts and 5 watts, consistent with standard low-draw interior lighting in 12-volt automotive electrical systems.
For the 2006-2007 model years, the specifications list a single 6411 bulb without positional subdivision, while the 1998-2000 model years specify the 6411 for both the driver side and passenger side front map light positions.
