Additional Notes

The Ferrari 512 TR uses the 168 bulb for its dome light across the 1992-1994 model years.
The 168 is classified as an ANSI standard bulb, meaning it conforms to a standardized specification recognized in the United States and Canada.
It belongs to the T10 form factor, which refers to a miniature wedge-base bulb. The wedge base design means the glass envelope itself acts as the retention mechanism, with no separate metal base or pins.
The 168 operates at 12 volts, consistent with the standard electrical system voltage found in passenger vehicles.
Its rated power draw is 4.9 watts, placing it in the low-wattage range typical of interior courtesy lighting applications.
The T10 wedge format is widely used across many vehicle makes and models, which means the 168 bulb is a broadly available replacement type rather than a proprietary or hard-to-source component.
