Additional Notes

The Kia Soul EV uses the 6418 bulb for the luggage compartment across the 2015-2018 model years.
The 6418 is an ANSI-standardized bulb designation recognized in both the United States and Canada.
It is a festoon-style bulb, meaning it is cylindrical in shape and mounts by pressing between two spring-clip contacts at each end rather than inserting into a socket.
The 6418 has a length of 36mm, which is a factor in physical fitment, as festoon bulbs must match the spacing between the contact 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, which must correspond to the clip size in the fixture.
The bulb operates at 12 volts, consistent with standard automotive electrical systems.
Its rated wattage is 5W, placing it in the low-power category typical of interior courtesy and cargo lighting applications.
Because festoon bulbs are defined by both length and base type, substituting a 6418 with a festoon bulb of a different length or base size would result in an improper fit even if the voltage and wattage match.
