Additional Notes

The Toyota T100 uses the 194 bulb size across all listed model years, spanning 1993-1998, for its instrument panel fitment.
The 194 is a miniature wedge-type bulb following the T10 form factor, which refers to a tubular glass envelope roughly 10 millimeters wide at its widest point.
The wedge base design means the bulb is held in place by the socket gripping the glass base directly, with no separate metal base or pins involved.
The 194 bulb operates at 12 volts and draws 3.78 watts, placing it in the low-wattage range typical of instrument panel illumination applications.
The 194 designation follows ANSI standardization, meaning the bulb conforms to a defined specification recognized across the United States and Canada.
Because the 194 is an ANSI-standardized part, it is produced by multiple manufacturers and is widely interchangeable at the specification level, though socket fit should be confirmed before substitution.
