Additional Notes

The Chevrolet Tracker uses the 168 bulb size for the map light across the 1999-2004 model years.
The 168 bulb follows the ANSI standard, meaning it conforms to a recognized North American specification used in both the United States and Canada.
This bulb is a miniature wedge type, designated T10, which refers to its wedge-base construction that allows it to be inserted and held in place without a separate socket locking mechanism.
The 168 bulb operates at 12 volts, consistent with the standard electrical system voltage found in passenger vehicles.
The rated wattage of the 168 bulb is 4.9W, placing it in the low-power range typical of interior courtesy and reading lights.
The T10 wedge base is a widely used form factor, meaning the 168 bulb shares physical fitment compatibility with several other bulb numbers that also use the T10 base, though wattage and brightness may differ between them.
