Additional Notes

The Chrysler Fifth Avenue uses the 168 bulb for the license plate position across all listed model years, spanning 1983-1989.
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.
The bulb follows the T10 form factor, which refers to a miniature wedge-base design. The wedge base eliminates the need for a separate metal contact, as the glass envelope itself forms the connection within the socket.
The 168 operates at 12 volts, consistent with the standard electrical system voltage found in conventional passenger vehicles of this era.
The rated wattage of the 168 is 4.9W, placing it in the low-power range typical of auxiliary lighting positions such as license plate illumination.
Because the 168 is an ANSI-standardized miniature wedge type, it is physically interchangeable with other bulbs sharing the T10 wedge base, provided voltage and wattage compatibility is also considered.
