Mercury Marauder high beam and low beam headlight bulbs utilize 9007 and H5001 sizes for high beam applications, with 9007 and H5006 sizes for low beam configurations. The replacement chart covers vehicle production spanning 1963 to 2004, detailing bulb specifications across 41 years of manufacturing.
The year-by-year compatibility chart below provides a quick reference to verify the correct bulb size for your vehicle.
The Mercury Marauder headlight specifications cover two distinct eras: the 2003-2004 revival and the 1963-1970 original production run, with each era using a completely different headlight technology.
The 9007 is a dual-filament halogen bulb operating at 12V with a wattage rating of 65W on high beam and 55W on low beam, fitted with a PX29t base. Its dual-filament design means a single bulb serves both the high beam and low beam functions in the 2003-2004 Marauder.
Because the 9007 handles both beam functions in the 2003-2004 Marauder, the high beam and low beam specifications for those years list the same bulb size rather than two separate units.
The 1963-1970 Marauder used sealed beam headlight units, which are self-contained glass assemblies where the lens, reflector, and filament form a single unit. When a sealed beam fails, the entire assembly is replaced rather than an internal bulb.
The H5001, used for high beam on the 1963-1970 Marauder, is a 4-inch square sealed beam unit rated at 12V. The H5006, used for low beam on those same years, is a 5.75-inch round sealed beam unit also rated at 12V. The two units are not interchangeable due to their differing shapes and sizes.
All three bulb types listed across the Marauder specifications conform to ANSI standards recognized in both the United States and Canada.
The shift from separate sealed beam units for high and low beams in the 1963-1970 models to a single dual-filament 9007 bulb in the 2003-2004 models reflects a fundamental difference in headlight system architecture between the two production periods.
Substituting an H5001 for an H5006, or vice versa, would not be a valid replacement given that the two units carry different form factors and serve different beam positions within the 1963-1970 headlight system.
