Additional Notes

The Dodge Grand Caravan uses the 168 bulb size for the license plate position across all model years from 1987 to 2019.
The 168 bulb is a miniature wedge type, classified under the T10 form factor, which refers to a tubular bulb roughly 10 eighths of an inch wide at its widest point.
The 168 bulb operates at 12 volts and draws 4.9 watts, placing it in the low-wattage range typical of exterior indicator and illumination positions.
The 168 is an ANSI-standardized bulb recognized in both the United States and Canada, meaning it conforms to a defined set of electrical and physical specifications shared across manufacturers.
The wedge base design of the 168 bulb means it is held in its socket by the tension of the base itself rather than by a separate locking mechanism or bayonet pins.
The T10 wedge format is shared by several bulb numbers, so substitutions from closely related types such as the 194 are sometimes attempted. However, the 194 operates at 3.78 watts rather than 4.9 watts, which represents a difference in output that may affect illumination levels.
Because the 168 bulb is an ANSI-standardized type, aftermarket and OEM-equivalent replacements from multiple suppliers are generally produced to the same voltage and wattage ratings as the original specification.
