The Chevrolet Metro side marker requires a 168 bulb size for the specific lighting component located on the exterior of the vehicle. Data for the specified bulb covers the range from 1998 to 2001.
The year-by-year compatibility chart below provides a quick reference to verify the correct bulb size for your vehicle.
The 168 bulb is the sole bulb size specified for the Chevrolet Metro across all listed side marker positions and model years.
Both the front and rear side marker positions on the Metro (1998-2001) share the same 168 bulb size, making the two positions interchangeable in terms of bulb fitment.
The 168 bulb follows the ANSI standard recognized in both the United States and Canada.
It is a miniature wedge type bulb, classified under the T10 designation, which refers to its tubular wedge-base form factor.
The 168 bulb operates at 12 volts, consistent with standard automotive electrical systems.
Its rated wattage of 4.9W places it in the low-power range, typical of small marker and clearance lighting applications.
The wedge base of the T10 format requires no separate metal base or bayonet pins, as the glass envelope itself acts as the retention mechanism within the socket.
Because the 168 specification is uniform across all four model years and both marker positions, no year-specific or position-specific fitment variations are present in the listed data.
