Additional Notes

The 192 bulb is the sole license plate bulb size listed for the Saturn Sky across the 2007-2010 model years.
The 192 bulb follows the ANSI standard recognized in both the United States and Canada, meaning it conforms to a defined set of electrical and physical specifications shared across North American markets.
It is a T10 miniature wedge type, which refers to a small, wedge-shaped base that seats directly into a socket without a separate metal cap or bayonet pin.
The bulb operates at 12 volts, consistent with the standard electrical system voltage found in passenger vehicles.
At 3 watts, the 192 draws a low amount of power relative to other automotive bulb applications such as headlights or brake lights.
The wedge base format of the T10 means the bulb is held in place by tension from the socket walls rather than by a locking mechanism, which affects how it is seated and removed.
The 192 designation is an ANSI trade number, a standardized identifier that allows bulbs from different manufacturers to be cross-referenced as electrically and physically equivalent when sharing the same number.
Because the 192 is an ANSI-standardized trade number, bulbs carrying that designation from different manufacturers are generally interchangeable within the same socket type.
