Additional Notes

The Ford Bronco II uses the 194 bulb for the license plate position across all model years from 1984-1990, making it a consistent fitment throughout the vehicle's entire production run.
The 194 is an ANSI-standardized bulb recognized in both the United States and Canada, meaning it conforms to a defined set of electrical and physical specifications rather than being a proprietary or regional-only part.
It belongs to the T10 wedge family, a miniature wedge base design that connects by pressing directly into a socket without a separate metal base or locking pins.
The 194 operates at 12 volts, which is consistent with the standard electrical system voltage found in conventional passenger vehicles.
Its rated wattage of 3.78W places it in the low-power range, reflecting the modest illumination demand of a license plate application.
Because the 194 is an ANSI-standardized type, it is produced by multiple manufacturers, and physical and electrical interchangeability with other 194-rated bulbs from different brands is generally expected within that standard.
The T10 wedge base format is shared by several other bulb types in the same family, though wattage and voltage ratings can differ between them, meaning socket compatibility alone does not confirm electrical equivalence.
