Lincoln MKZ Headlight Bulb Size

Lincoln MKZ high beam headlight bulbs utilize D3S, 9005, or H7 sizes, while low beam headlight bulbs use D3S, 9005, or H11 sizes depending on model generation. The replacement chart covers 2007 through 2020 model years with corresponding bulb size specifications.

Additional Notes

The D3S bulb is a mercury-free HID xenon type operating at 42V and 35W, built to ECE standards with a PK32d-5 base and an integral ignitor. It is specified for both high beam and low beam positions on the Lincoln MKZ for the 2017-2020 model years, exclusively in vehicles equipped with HID headlamps.
The D1S bulb is an earlier HID xenon type rated at 85V and 35W, also carrying an integral ignitor and a PK32d-2 base. It appears in the low beam position on the Lincoln MKZ for 2007-2009 model years when fitted with HID headlamps, distinguishing it from the D3S used in later years.
Although both D1S and D3S bulbs share the same 35W power rating and integral ignitor design, their base types differ: PK32d-2 for the D1S and PK32d-5 for the D3S. These bases are not interchangeable, and substituting one for the other is not supported by the specifications.
The H11 bulb is a single-filament halogen type rated at 12V and 55W, conforming to ECE standards with a PGJ19-2 base. It is listed as the low beam bulb for halogen capsule headlamp configurations across the 2007-2012 model years of the MKZ.
The 9005 bulb follows ANSI standards rather than ECE standards and operates at 12V and 65W through a P20d base. It is listed for both high beam and low beam positions on the MKZ for 2010-2012, making it the highest-wattage halogen type in these specifications.
The H7 bulb is a single-filament halogen type rated at 12V and 55W with a PX26d base, holding ECE approval as well as acceptance in the US and Japan. It is specified for the high beam position on the MKZ across 2007-2009, and also appears alongside the 9005 in the high beam position for 2010-2012.
For the 2010-2012 model years, the low beam position lists three distinct bulb sizes: the 9005, the H11 for halogen capsule headlamps, and the D3S for HID headlamps. This reflects multiple headlamp system configurations available during those years, each requiring a different and incompatible bulb type.
The H11 and H7 bulbs both operate at 12V and 55W but use different base types, PGJ19-2 and PX26d respectively, and serve different positions within the headlamp system. The H11 is assigned to low beam applications while the H7 is assigned to high beam applications in the halogen configurations of the MKZ.
