Additional Notes

The Ford F-150 high beam indicator uses the 194 bulb size across all listed model years from 1975 to 1998.
The 194 is a miniature wedge bulb built to the T10 form factor, which refers to its tubular glass envelope width of 10 eighths of an inch.
The wedge base design means the 194 bulb is held in place by the socket gripping the glass base directly, with no separate metal base or pins required.
The 194 operates at 12 volts and draws 3.78 watts, placing it in the low-wattage range typical of instrument panel and indicator lighting.
The 194 conforms to ANSI standards recognized in both the United States and Canada, meaning it meets a defined set of electrical and physical specifications shared across those markets.
Because the 194 is an ANSI-standardized bulb, units from different manufacturers are generally interchangeable as long as they carry the same designation.
The T10 wedge format is widely used in dashboard and indicator applications across many vehicle makes, which contributes to broad retail availability of the 194 bulb.
