Additional Notes

The Chevrolet Cavalier glove box uses the 194 bulb across all listed model years, spanning 1983-1989 and 1991-2005.
The 194 is a miniature wedge-type bulb, classified under the T10 form factor, which refers to a tubular glass envelope roughly 10 eighths of an inch wide.
The wedge base design means the bulb is held in its socket by the tension of the socket walls against the glass pinch at its base, with no separate metal base or bayonet pins involved.
The 194 operates at 12 volts and draws 3.78 watts, placing it among the lower-wattage bulbs used in automotive interior applications.
The 194 conforms to ANSI standards recognized in both the United States and Canada, indicating a standardized specification for voltage, wattage, and physical form.
Because the 194 is an ANSI-standardized T10 wedge bulb, it is interchangeable with other bulbs sharing the same base type and electrical ratings, provided those substitutes also meet the 12V, 3.78W specification.
Substituting a wedge bulb of a different wattage rating into the Cavalier glove box socket carries a risk of either insufficient illumination or excessive heat generation within the socket housing.
