Additional Notes

The 168 bulb is the license plate bulb size for the INFINITI M30 across all listed model years, spanning 1990-1992.
The 168 bulb follows the ANSI standard, which is the American National Standards Institute's classification system used in the United States and Canada to define bulb specifications.
It is a miniature wedge-type bulb, designated T10, where "T" refers to the tubular shape and "10" indicates the width in eighths of an inch.
The 168 bulb operates at 12 volts, consistent with the standard electrical system voltage found in passenger vehicles.
Its rated wattage is 4.9W, which places it in the low-power range typical of license plate and courtesy lighting applications.
The wedge base design means the bulb is held in place by tension from the socket contacts rather than a bayonet or screw mechanism, which affects socket compatibility when replacing the bulb.
