Additional Notes

The 6411 bulb is the dome light specification for the Mercedes-Benz E250 across the 2014-2016 model years.
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 inserting into a socket.
The bulb measures 36mm in length, which is the critical fitment factor for festoon bulbs, as the housing clip spacing must match this figure.
It uses an SV8.5 base designation, which refers to the metal end cap style standard to this festoon format.
The 6411 operates at 12 volts and draws 5 watts, consistent with low-power interior lighting applications.
The 6411 designation follows the ANSI standardization system used in the United States and Canada, meaning equivalent bulbs sold under this code from different manufacturers share the same electrical and physical specifications.
