Additional Notes

The Chevrolet Tracker uses two distinct bulb sizes for the license plate position across its model years: the 168 and the 194.
Both the 168 and 194 are ANSI-standardized bulbs recognized in the United States and Canada, and both follow the T10 miniature wedge form factor.
The T10 wedge base is a small, wedge-shaped base that seats directly into a socket without a separate metal cap, which is a common design in low-current automotive lighting applications.
Although the 168 and 194 share the same T10 wedge base, they are not electrically identical, as the 168 operates at 4.9W while the 194 operates at 3.78W on a 12V circuit.
The wattage difference between the two bulbs means that substituting one for the other may result in a brightness level that does not match the original factory specification for that model year.
The Chevrolet Tracker (1999-2004) uses the 168 bulb for the license plate position across six consecutive model years.
The 1998 Chevrolet Tracker uses the 194 bulb for the license plate position, making it the sole model year in the listed range to carry that specification.
