Additional Notes

The 194 bulb is the sole instrument panel bulb size specified for the Toyota Crown across the 1969-1972 model years.
The 194 is an ANSI-standardized miniature wedge bulb, classified under the T10 form factor, and operates at 12 volts with a power draw of 3.78 watts.
The T10 wedge base design means the bulb is held in its socket by the tension of the base itself, with no separate locking mechanism or bayonet pins involved.
The ANSI standardization of the 194 bulb applies to both the United States and Canada, meaning the same bulb specification is valid across both markets for this application.
At 3.78 watts, the 194 bulb falls within the low-wattage range typical of instrument panel illumination, where heat output and space constraints are primary considerations.
