Additional Notes

The Plymouth Laser uses the 168 bulb for the license plate position across the 1990-1994 model years.
The 168 is an ANSI-standardized bulb type, meaning its specifications are governed by a recognized North American standard applicable in both the United States and Canada.
It belongs to the T10 form factor, a miniature wedge-base design that does not use a separate metal base or pins, relying instead on the tapered plastic wedge of the bulb itself to make electrical contact within the socket.
The 168 operates at 12 volts, consistent with the standard electrical system voltage found in conventional passenger vehicles.
Its rated power draw is 4.9 watts, placing it in the low-wattage range typical of auxiliary lighting positions such as license plate illumination.
The T10 wedge base format is shared by several bulb numbers in the same family, including the 194 and 161, which can create interchangeability confusion despite differences in wattage or light output between those types.
