Additional Notes

The 194 bulb is the sole bulb type listed for the Ford Fiesta ash tray application, appearing across both available model years, 1979-1980.
The 194 is an ANSI-standardized bulb used in the United States and Canada, classified as a miniature wedge type with a T10 form factor.
The T10 designation refers to the bulb's tubular shape, with the number indicating a width of 10 eighths of an inch, a sizing convention standard in miniature automotive bulbs.
The 194 operates at 12 volts with a power draw of 3.78 watts, consistent with low-current interior lighting circuits typical of instrument and convenience lighting applications.
The wedge base design of the 194 means the bulb is held in its socket by the tension of the base itself rather than by a bayonet or screw mechanism, which is a common trait in small interior automotive bulbs.
