Additional Notes

The 6411 is the dome light bulb size for the Audi Allroad across the 2013-2016 model years.
The 6411 bulb follows the ANSI standard, making it a recognized specification in both the United States and Canada.
The 6411 is a festoon-type bulb, meaning it is cylindrical in form and mounts by pressing between two spring clips at each end rather than inserting into a socket.
The 6411 bulb has a 36mm length and uses an SV8.5 base, which refers to the diameter of the metal end caps on a festoon bulb.
The 6411 operates at 12 volts and draws 5 watts, placing it in the low-wattage range typical of interior automotive lighting.
The 2017 Audi Allroad dome light uses an LED unit in place of the 6411 incandescent bulb used in prior model years.
Because the 2017 model uses an integrated LED rather than a numbered bulb size, the festoon socket fitment of earlier models does not apply to that year.
