Additional Notes

The Porsche 968 uses the 6411 bulb for the dome light across all documented model years, spanning 1992-1995.
The 6411 is an ANSI-standardized bulb designation, meaning it conforms to a defined set of electrical and physical specifications recognized across the United States and Canada.
The 6411 is a festoon-type bulb, which is a cylindrical lamp that mounts by pressing its two end caps into spring clips rather than inserting into a socket.
The 6411 bulb has a length of 36mm, which is the critical fitment factor for festoon bulbs, as the spring clip housing must match the bulb's end-to-end length.
The 6411 uses an SV8.5 base, a designation that refers to the 8.5mm cap width on each end of the festoon body.
The bulb operates at 12 volts and draws 5 watts, consistent with standard low-current interior lighting in 12-volt automotive electrical systems.
Because festoon bulbs are sized by length and cap width, substituting a 6411 with a festoon bulb of a different length or base size would result in an improper fit in the Porsche 968 dome light housing.
