Additional Notes

The Honda Insight uses the 168 bulb size for the license plate position across all listed model years from 2000-2006 and 2010-2014.
The 168 bulb is classified as 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 in the low-wattage range typical of auxiliary lighting positions such as license plate illumination.
The 168 designation follows ANSI standardization, meaning it is a recognized specification shared across the United States and Canada rather than a proprietary or region-specific part number.
Because the 168 is a wedge-base bulb, it is physically interchangeable with other T10 wedge bulbs that share the same base format, though wattage and voltage ratings must match the original specification for proper function.
The T10 wedge format is one of the most widely produced miniature bulb bases, which means the 168 bulb has broad cross-compatibility with aftermarket and OEM replacement options that conform to the same ANSI rating.
