Additional Notes

The Ford Ranger uses the 194 bulb for its turn signal indicator across all listed model years from 1983-2003.
The 194 is classified as a miniature wedge bulb, designated T10 in the international bulb sizing system.
The T10 designation refers to the bulb's tubular shape, with the number indicating its width in eighths of an inch.
The 194 bulb operates at 12 volts, which is consistent with the standard electrical system voltage found in passenger vehicles and light trucks.
At 3.78 watts, the 194 is a low-wattage bulb, typical for indicator and courtesy lighting applications rather than primary illumination.
The 194 bulb conforms to ANSI standards, meaning its specifications are recognized across both the United States and Canada.
The wedge base design of the 194 means it is held in its socket by the tension of the base itself, without a separate metal bayonet or screw fitting.
Because the 194 is an ANSI-standardized part, it is produced by multiple manufacturers, and units from different brands are generally interchangeable provided the voltage and wattage ratings match.
