Additional Notes

The Dodge Viper uses the 168 bulb for its license plate lighting across all model years listed in the specifications, spanning 1992-2010.
The 168 is a T10 miniature wedge bulb, meaning it uses a wedge-shaped base rather than a screw or bayonet fitting, and is inserted directly into a wedge-style socket.
The 168 bulb operates at 12 volts with a power draw of 4.9 watts, placing it in the low-wattage range typical of license plate and courtesy lighting applications.
The 168 is an ANSI-standardized bulb recognized in both the United States and Canada, meaning the designation refers to a consistent, defined specification rather than a proprietary part number.
The T10 designation refers to the bulb's tubular envelope size, where "10" indicates a width of ten-eighths of an inch, a common form factor shared by several miniature wedge bulb variants.
Because the 168 and certain other T10 wedge bulbs share the same base type, physical fitment alone does not confirm electrical compatibility, and wattage ratings should be matched to the original specification to avoid socket or wiring issues.
