Additional Notes

The Pontiac Sunbird uses the 194 bulb for its license plate lighting across all model years listed in the specifications.
The 194 is an ANSI-standardized bulb type, meaning its specifications are governed by a recognized North American standard applicable in both the United States and Canada.
This bulb follows the T10 wedge form factor, which refers to a miniature wedge-base design that seats without a separate metal base or locking pins, relying instead on the wedge shape of its glass envelope to hold it in the socket.
The 194 bulb operates at 12 volts, consistent with the standard electrical system voltage found in conventional passenger vehicles.
At 3.78 watts, the 194 draws a relatively low amount of power, which is typical for license plate and other small indicator lighting applications.
The Pontiac Sunbird (1976-1980) shares the same 194 bulb specification as the 1989-1994 model years, indicating consistent socket compatibility across two distinct production periods.
Because the 194 is a wedge-base bulb, it is physically interchangeable with other T10 wedge bulbs of the same voltage rating, though wattage differences in substitute bulbs may affect socket heat tolerance.
