Additional Notes

The Dodge Aries uses the 168 bulb for the license plate position across all model years covered in the specifications, spanning 1981-1989.
The 168 bulb is a miniature wedge type, classified under the T10 form factor, which refers to a tubular bulb body approximately 10 millimeters wide at its widest point.
The wedge base design means the 168 bulb has no metal pins or a separate base cap; instead, the glass envelope itself is pinched at the bottom to form the electrical contact points.
The 168 bulb operates at 12 volts and draws 4.9 watts, placing it among the lower-wattage bulbs in automotive lighting applications.
The 168 is an ANSI-standardized bulb, meaning its physical and electrical specifications are governed by a recognized industry standard applicable in both the United States and Canada.
Because the 168 follows an ANSI standard, replacement bulbs from different manufacturers carrying the same designation are expected to share identical base type, voltage, and wattage characteristics.
The T10 wedge format is shared by several related bulb numbers, including the 194 and 161, though those carry different wattage ratings and are not direct substitutes for the 168 without verifying socket and circuit compatibility.
