Additional Notes

The Chevrolet Beretta glove box uses two distinct bulb sizes across its production run: the 168 and the 194, both of which are ANSI-standardized miniature wedge bulbs of the T10 type rated at 12 volts.
The 168 bulb was fitted in the 1991-1993 model years, while the 194 bulb was used in the 1987-1989 model years.
Although both bulbs share the same T10 wedge base and 12-volt operating voltage, they differ in wattage. The 168 draws 4.9 watts, whereas the 194 draws 3.78 watts.
The shared T10 wedge base between the 168 and 194 means the two bulbs are physically interchangeable in terms of socket fitment, though their wattage ratings differ and they are not electrically identical.
The T10 designation refers to a tubular bulb form with a width of approximately 10 millimeters, a format widely used in low-current interior lighting applications such as glove boxes.
ANSI standardization for both bulbs indicates that the 168 and 194 specifications are governed by a common North American technical standard, ensuring consistent electrical and physical characteristics across manufacturers.
