Additional Notes

The 168 bulb is the sole license plate bulb type listed for the Sterling 825, covering the 1987-1988 model years.
The 168 bulb follows the ANSI standard recognized in both the United States and Canada, classifying it as a miniature wedge type within the T10 form factor.
The T10 designation refers to a wedge-base bulb with a tubular envelope roughly 10 eighths of an inch wide, designed to press directly into a socket without a separate metal base.
The 168 bulb operates at 12 volts with a power draw of 4.9 watts, consistent with low-current automotive auxiliary lighting applications such as license plate illumination.
The wedge base design of the 168 bulb means fitment depends on socket compatibility with the T10 form factor, and substitutions using different base types would not be interchangeable regardless of voltage or wattage similarity.
