Additional Notes

The Acura NSX uses the 168 bulb size for the license plate position across every listed model year, spanning 1995-2005.
The 168 bulb is classified as a miniature wedge type, designated T10, which refers to its wedge-style base that seats directly into a socket without a separate metal base or pins.
The 168 bulb operates at 12 volts and draws 4.9 watts, placing it among the lower-wattage bulbs in automotive applications, consistent with a license plate illumination role.
The 168 designation follows ANSI standardization, meaning the specification is recognized across both the United States and Canada.
T10 wedge bulbs are a widely produced form factor, and the 168 rating specifically defines the electrical characteristics that a replacement must match for correct operation in the Acura NSX license plate socket.
Because the 168 is an ANSI-standardized bulb, aftermarket and OEM replacements from different manufacturers are generally interchangeable as long as the T10 wedge base and 12V/4.9W ratings are maintained.
