Additional Notes

The 194 bulb is the sole license plate bulb size listed for the Oldsmobile Aurora across all model years in the specifications, spanning 1995-1999 and 2001-2003.
The 194 bulb follows the ANSI standard recognized in both the United States and Canada, meaning it conforms to a defined set of electrical and physical requirements shared across North American markets.
It is classified as a T10 miniature wedge bulb, a designation that refers to its tubular glass envelope and wedge-shaped base, which seats directly into a socket without a separate metal base or pins.
The 194 operates at 12 volts, consistent with the standard electrical system voltage found in passenger vehicles.
Its rated wattage of 3.78W places it in the low-power range, which is typical for license plate illumination, where output requirements are modest compared to forward lighting.
The T10 wedge format is widely shared across many vehicle makes and models, which means the 194 bulb has broad cross-compatibility in the aftermarket. However, fitment in the Oldsmobile Aurora is confirmed only for the license plate position as listed in these specifications.
Because the 194 designation is an ANSI-standardized type, replacement bulbs from different manufacturers carrying the same designation are expected to share the same voltage, wattage, and base configuration.
