Additional Notes

The Jaguar Vanden Plas uses the 6411 bulb size for the dome light across all listed model years from 1982 to 2009, with the exception of 1998-2003, which are not present in the specifications.
The 6411 is a festoon-style bulb, meaning it is cylindrical in shape and makes contact at both ends rather than through a screw or bayonet base.
The 6411 bulb follows the ANSI standard, which is the recognized specification body for bulb classifications in the United States and Canada.
The bulb operates at 12 volts and 5 watts, which is consistent with low-power interior lighting applications in passenger vehicles.
The 6411 uses an SV8.5 base, a designation that refers to a festoon base with an 8.5mm cap width, which determines physical fitment within the dome light housing.
The 36mm length of the 6411 bulb is a critical fitment factor, as festoon bulbs must match the span of the socket contacts to seat and function correctly.
Because festoon bulbs are defined by both length and base width, substituting a bulb that differs in either specification would result in an improper fit, even if the voltage and wattage ratings match.
