Additional Notes

The 168 bulb is the map light specification for the Isuzu Amigo across all listed model years, 1989-1994.
The 168 bulb follows the ANSI standard, meaning it conforms to a recognized North American specification used in both the United States and Canada.
It is a miniature wedge-type bulb, classified under the T10 designation, which refers to its tubular shape with a wedge base that connects without a separate metal socket pin.
The wedge base design means the bulb is held in place by tension from the socket itself rather than by a bayonet or screw mechanism.
The 168 operates at 12 volts, consistent with the standard electrical system voltage found in conventional passenger vehicles and light trucks.
Its rated wattage is 4.9W, placing it in the low-power range typical of interior courtesy and map lighting applications.
The T10 wedge form factor is shared by several bulb numbers in the same family, which means physical fitment alone does not confirm electrical compatibility when substituting an alternative bulb.
