Additional Notes

The 168 bulb is the sole map light bulb type listed for the Ferrari 348 GTB across the 1993-1994 model years.
The 168 is an ANSI-standardized bulb used in the United States and Canada, operating at 12 volts with a power draw of 4.9 watts.
It follows the T10 miniature wedge form factor, a base type that relies on two angled retention tabs rather than a threaded or bayonet-style socket.
The T10 wedge base is a widely used automotive format, and bulbs sharing this base type are physically interchangeable in terms of fitment, though wattage and voltage ratings must match the original specification to avoid electrical or lighting issues.
