Additional Notes

The 1991-1993 Isuzu Stylus uses the 168 bulb for the license plate position across all three model years.
The 168 is an ANSI-standardized bulb type, meaning it conforms to a defined set of electrical and physical specifications recognized across the United States and Canada.
The 168 bulb is a miniature wedge type, designated T10, which refers to its tubular glass envelope and wedge-style base that seats directly into a socket without a separate metal base or pins.
The 168 operates at 12 volts and draws 4.9 watts, placing it in the low-wattage range typical of license plate and courtesy lighting applications.
The wedge base design of the T10 means fitment depends on socket compatibility with that base style, and substituting a bulb with a different base type would not be physically interchangeable regardless of voltage or wattage similarity.
