Additional Notes

The Ford Focus (2008-2011) uses the 6418 bulb for the license plate position across all four model years listed.
The 6418 is a festoon-style bulb, meaning it is cylindrical and mounts by pressing between two spring clips rather than inserting into a socket.
The 6418 bulb measures 36mm in length, which is a standard festoon size found in many license plate and interior lighting applications.
It uses an SV8.5 base, a designation that refers to the contact cap style used on festoon bulbs with a nominal 8.5mm cap width.
The 6418 operates at 12 volts and draws 5 watts, placing it in the low-wattage range typical of license plate lighting.
The 6418 carries an ANSI designation, meaning it conforms to a standardized specification recognized in both the United States and Canada.
Because the 6418 is an ANSI-standardized part, bulbs from different manufacturers carrying the same number are expected to share the same electrical and physical characteristics.
