Additional Notes

The Ford Five Hundred uses the 212-2 bulb for the map light across the 2005-2007 model years.
The 212-2 is an ANSI-standardized bulb type, meaning its physical and electrical specifications conform to a defined North American standard recognized in both the United States and Canada.
The 212-2 is a festoon-style bulb, which is a cylindrical lamp that mounts by pressing its two end caps into spring clips rather than inserting into a socket.
The bulb measures 41mm in length, which is the span between the two end contacts and determines whether it fits the fixture's clip spacing.
The 212-2 uses an SV8.5 base, a designation that refers to the end-cap style used on festoon bulbs with an 8.5mm cap width.
The bulb operates at 12 volts, consistent with the standard electrical system voltage found in passenger vehicles.
The 212-2 carries a 12-watt rating, which reflects its power draw and influences the brightness output for interior map lighting use.
When substituting the 212-2, the replacement bulb must match the 41mm festoon length and SV8.5 base to seat correctly in the Ford Five Hundred's map light housing.
