Oldsmobile Aurora License Plate Bulb Size

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.
