Additional Notes

The Ferrari F355 Spider uses the 168 bulb size for its map light across all documented model years, spanning 1996-1999.
The 168 bulb is classified under the ANSI standard, meaning it conforms to a recognized North American specification used in the United States and Canada.
This bulb follows the T10 form factor, a miniature wedge-base design that connects by pressing directly into a wedge-style socket without a separate metal base or pins.
The 168 operates at 12 volts, which is consistent with the standard electrical system voltage found in conventional passenger vehicles.
At 4.9 watts, the 168 is a low-power bulb, typical of interior courtesy and reading light applications where prolonged use and minimal heat output are practical considerations.
The T10 wedge base is a widely used form factor, and multiple bulb numbers share this physical base type, meaning not all T10-base bulbs are electrically interchangeable with the 168 despite fitting the same socket.
