Additional Notes

The Chevrolet Venture map light uses one of two bulb sizes across its model years: the 192 for 2000-2005 and the 168 for 1997-1999.
Both the 192 and 168 are ANSI-standardized bulbs recognized in the US and Canada, meaning they conform to a defined set of electrical and physical standards rather than being proprietary to a specific manufacturer.
Both bulbs share the T10 miniature wedge form factor, a small wedge-base design that seats directly into a socket without a separate metal base or locking pins.
Both bulbs operate at 12 volts, which is consistent with standard automotive electrical systems.
The 192 bulb is rated at 3 watts, while the 168 bulb is rated at 4.9 watts. Despite sharing the same T10 wedge base, the difference in wattage means the two are not electrically interchangeable without affecting light output.
Because the 192 and 168 share the T10 physical form factor, one may fit into the socket of the other, but the wattage difference represents a meaningful electrical distinction between the two.
