Additional Notes

The Mercedes-Benz ML55 AMG uses the 6411 bulb for the map light across the 2000-2003 model years.
The 6411 is an ANSI-standardized bulb type, meaning its physical and electrical specifications are governed by a recognized North American standard used in both the United States and Canada.
The 6411 is a festoon-style bulb, which is a cylindrical lamp that mounts by pressing its two end caps into spring clips rather than twisting or plugging into a socket.
The 6411 bulb has a 36mm length, which is a critical fitment factor, as festoon bulbs must match the exact span between the mounting clips in the housing.
The SV8.5 base designation refers to the end cap style of the festoon bulb, with 8.5mm indicating the cap width, which must correspond to the clip width in the fixture.
The 6411 operates at 12 volts and 5 watts, consistent with standard low-current interior lighting in 12-volt automotive electrical systems.
Because festoon bulbs are available in multiple lengths, a replacement bulb must match the 36mm specification of the 6411 to seat correctly in the ML55 AMG map light housing.
