Additional Notes

The Volkswagen Scirocco uses the 6411 bulb size for the dome light across all listed model years, spanning 1975-1988.
The 6411 is classified as a festoon bulb, meaning it is cylindrical in shape and mounts by pressing its end caps into spring clips rather than using a socket.
This bulb follows the ANSI standard, indicating it meets the specifications recognized in both the United States and Canada.
The 6411 has a 36mm length, which is a critical fitment factor, as festoon bulbs must match the exact span between the spring clips in the housing.
The base type is SV8.5, a designation that refers to the diameter of the metal end caps on the festoon bulb, and it must correspond to the clip width in the fixture.
The 6411 operates at 12 volts, consistent with the standard electrical system voltage found in passenger vehicles of this era.
The bulb carries a 5-watt rating, placing it in the low-wattage range typical of interior courtesy lighting applications.
Because the 6411 is an ANSI-designated bulb, it is subject to standardized tolerances for voltage, wattage, and physical size, which supports cross-brand interchangeability within that specification.
