Additional Notes

The Mercedes-Benz E320 uses the 6411 bulb size for the dome light across all listed model years from 1994 to 2009.
The 6411 is classified as a festoon bulb, meaning it is a cylindrical lamp that mounts by pressing its end caps into spring clips rather than inserting into a socket.
The 6411 bulb has a length of 36mm, which is a critical physical specification, as festoon bulbs must match the exact length of the housing to seat correctly in the spring clip retainers.
The 6411 uses an SV8.5 base, a designation that refers to the end cap style and the 8.5mm cap width used on festoon-type bulbs.
The 6411 operates at 12 volts and 5 watts, which is consistent with standard low-draw interior lighting in passenger vehicles.
The 6411 designation follows the ANSI standard used in the United States and Canada, meaning it is part of a standardized naming system that defines the bulb's physical and electrical properties.
Because the 6411 is an ANSI-standardized bulb, other bulbs sharing the same 36mm length, SV8.5 base, 12V rating, and 5W rating may be physically and electrically interchangeable, provided those parameters match exactly.
