Additional Notes

The Isuzu Rodeo uses the 168 bulb for the license plate position across all listed model years, spanning 1991-2004.
The 168 bulb is a T10 miniature wedge type, which refers to its wedge-shaped base that holds the bulb in place without a separate metal socket or pins.
This bulb operates at 12 volts and draws 4.9 watts, placing it among the lower-wattage bulbs used in automotive exterior lighting applications.
The 168 designation follows ANSI standardization, meaning the bulb is produced to a consistent specification recognized across the United States and Canada.
T10 wedge bulbs are a widely used format in automotive license plate and interior lighting, and the 168 shares this base type with several other bulb numbers in the same family, such as the 194, though those carry different wattage ratings and are not interchangeable without accounting for that difference.
Because the Isuzu Rodeo specifies the 168 rather than the 194, substituting a 194 would result in a slightly different wattage output, which may affect brightness and long-term socket compatibility.
