Additional Notes

The 168 bulb is the specified license plate bulb size for the Ford Taurus X across its 2008-2009 model years.
The 168 bulb follows the ANSI standard recognized in both the United States and Canada, classifying it as a standardized miniature wedge type designated T10.
T10 refers to the bulb's tubular shape, with the number indicating its width in eighths of an inch, making it a compact form factor suited to tight mounting spaces such as license plate housings.
The 168 operates at 12 volts, which aligns with the standard electrical system voltage found in passenger vehicles.
Its rated wattage of 4.9W places it in the low-power range typical of auxiliary and indicator lighting rather than primary illumination.
The wedge base design of the T10 means the bulb is held in its socket by the tension of the base itself, with no separate metal contact pins or bayonet lugs involved in the connection.
Because the 168 is an ANSI-standardized type, it shares its base and envelope dimensions with several other bulb numbers in the same family, though wattage and voltage ratings can differ between those related types, making direct substitution a matter requiring attention to the specific electrical ratings.
