Additional Notes

The Dodge Omni uses the 168 bulb for the license plate position across all model years from 1978 to 1990.
The 168 is a miniature wedge bulb, classified under the T10 form factor, which refers to a tubular bulb body approximately 10 eighths of an inch wide.
The wedge base design means the bulb is held in place by the socket gripping the glass envelope directly, with no separate metal base or pins involved.
The 168 bulb operates at 12 volts and draws 4.9 watts, placing it in the low-wattage range typical of auxiliary lighting functions such as license plate illumination.
The 168 is an ANSI-standardized bulb, meaning its electrical and physical specifications are defined by a recognized North American standard applicable in both the United States and Canada.
Because the 168 is a standardized type, it is interchangeable with any other 168-rated bulb from different manufacturers, provided the voltage and wattage ratings match.
T10 wedge bulbs share a socket type with several other bulb numbers in the same family, though substituting a different number from that family may result in mismatched wattage or light output for the license plate application.
