Additional Notes

The Chevrolet Corsica ash tray uses two distinct bulb sizes across its production run: the 161 and the 168, both of which are ANSI-standardized miniature wedge bulbs of the T10 type rated at 12 volts.
Although the 161 and 168 share the same T10 wedge base and 12-volt rating, they are not interchangeable due to a significant difference in wattage: the 161 draws 1 watt, while the 168 draws 4.9 watts.
The 161 bulb is specified for the Chevrolet Corsica across the 1990-1993 and 1995-1996 model years, making it the more frequently used of the two bulb types for this application.
The 168 bulb is specified for the 1987-1989 and 1994 model years.
The T10 designation refers to a tubular bulb form with a wedge base, a common format in low-voltage automotive interior lighting applications.
The wattage difference between the 161 and the 168 means the 168 produces noticeably more heat during operation, a relevant consideration given the confined space of an ash tray housing.
Both bulb types conform to ANSI standards applicable in the United States and Canada, indicating standardized physical and electrical tolerances across manufacturers.
The 1994 model year stands apart from the surrounding years in that it uses the 168 rather than the 161, representing a single-year reversion to the higher-wattage specification.
