Additional Notes

The Ferrari 348 Spider uses the 168 bulb size for the map light across the 1993-1995 model years.
The 168 bulb is an ANSI-standardized type recognized in the United States and Canada, which means it conforms to a defined set of electrical and physical parameters shared across manufacturers.
It is a miniature wedge-base bulb, classified under the T10 designation, which refers to its tubular shape and wedge-style base that locks into a socket without a separate metal cap or pins.
The bulb operates at 12 volts, consistent with standard automotive electrical systems.
Its rated wattage of 4.9W places it in the low-power range, typical of interior courtesy and reading light applications.
The wedge-base design of the T10 type means fitment depends on socket compatibility with that specific base style, and substituting a bulb with a different base type would not be physically interchangeable.
