Mercury Milan high beam and low beam headlight bulbs utilize 9005 and H7 sizes for high beam applications, with 9005 and H11 sizes for low beam configurations. The replacement chart covers 2006 through 2011 model years with corresponding bulb size specifications.
The year-by-year compatibility chart below provides a quick reference to verify the correct bulb size for your vehicle.
The Mercury Milan uses two distinct headlight bulb configurations across its production run. The 2006-2009 model years use H7 bulbs for high beam and H11 bulbs for low beam, while the 2010-2011 model years use the 9005 bulb for both high and low beam positions.
The 9005 bulb operates under the ANSI standard, which governs bulb specifications in the United States and Canada. It features a single filament, a P20d base, and is rated at 12V and 65W.
The H7 bulb operates under the ECE standard, which is the regulatory framework used in Europe and many other markets worldwide. It carries a PX26d base, runs at 12V, and is rated at 55W. Despite its ECE origin, the H7 is also approved for use in the United States and Japan.
The H11 bulb also follows the ECE standard and uses a PGJ19-2 base at 12V and 55W. It holds approval for use in the United States in addition to its primary ECE markets.
The 9005 is rated at 65W, while both the H7 and H11 are rated at 55W. This wattage difference reflects a higher power draw for the 9005, which is a relevant factor when considering electrical load on the vehicle's lighting circuit.
The P20d base of the 9005, the PX26d base of the H7, and the PGJ19-2 base of the H11 are physically distinct and not interchangeable with one another. Installing a bulb with an incorrect base type is not possible without modification to the socket.
For the Mercury Milan, the shift from H7 and H11 bulbs to the 9005 for both beam positions in 2010-2011 means that replacement bulbs for earlier and later model years are not cross-compatible, even within the same vehicle nameplate.
