Additional Notes

The Plymouth Sundance uses the 168 bulb for the license plate position across all listed model years, spanning 1987-1994.
The 168 is classified as a miniature wedge bulb, designated T10 in the tubular lamp sizing system, where "T10" refers to a tubular form factor measured in eighths of an inch.
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, which is consistent with standard automotive electrical systems.
Its rated wattage of 4.9W places it in the low-power range typical of auxiliary lighting positions such as license plate illumination.
The 168 carries ANSI standardization recognized in both the United States and Canada, meaning the specification reflects a formally defined and regulated bulb type rather than a proprietary one.
Because the 168 is an ANSI-standardized T10 wedge type, it shares physical and electrical compatibility with several other bulb numbers in the same family, though substitutions should be verified against wattage tolerances for the specific socket.
