Additional Notes

The Chevrolet Metro uses the 168 bulb for the license plate position across the 1998-2001 model years.
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 with a wedge-style base that clips directly into a socket without a separate metal base or pins.
The 168 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 recognized in both the United States and Canada, meaning units sourced from either market conform to the same electrical and physical specifications.
The T10 wedge base format is shared across a wide range of automotive bulb part numbers, so fitment verification by wattage and voltage rating is relevant when considering substitutions, as physically compatible bulbs may carry different electrical ratings.
