The Lincoln Capri high beam and low beam headlight bulb sizes include H5001, H6024, and H6006 options, with replacement specifications varying by bulb size across different production years. The chart documents headlight bulb specifications covering 1952 through 1959 model years.
The year-by-year compatibility chart below provides a quick reference to verify the correct bulb size for your vehicle.
The H6006 is the most consistently used sealed beam type across the Lincoln Capri's headlight specifications, appearing in both high beam and low beam positions for the 1952-1955 model years. It is a 5x7-inch rectangular sealed beam unit operating at 12V and conforming to ANSI standards for the US and Canada.
All four bulb types present in these specifications, H5001, H5006, H6024, and H6006, are sealed beam units. This means the entire lens, reflector, and filament assembly functions as a single unit, and the whole assembly is replaced rather than an individual bulb.
The H6024 is a 7-inch round sealed beam unit rated at 12V. It serves both the high beam and low beam positions on the Lincoln Capri for the 1956-1957 model years, making it the only type in these specifications to fulfill both functions with a single part number.
For the 1958-1959 model years, the Lincoln Capri uses two distinct sealed beam types depending on the beam function. The high beam position uses the H5001, a 4-inch square unit, while the low beam position uses the H5006, a 5.75-inch round unit, both rated at 12V.
The H5001 and H5006 are physically different in shape and size, which means they are not interchangeable with each other or with the H6024 and H6006 units used in earlier model years. Substituting one sealed beam type for another would require a compatible housing and mounting configuration.
All sealed beam types in these specifications conform to ANSI standards applicable in both the United States and Canada, indicating a standardized fitment framework shared across North American markets during this period.
The transition from the rectangular H6006 unit to the round H6024 between the 1955 and 1956 model years represents a change in both the physical form and the headlight housing required, as the two units differ in shape and cannot be used interchangeably.
The shift from the H6024 to separate H5001 and H5006 units between the 1957 and 1958 model years corresponds with a move to a dual-headlight system, where dedicated sealed beam units handle high and low beam functions independently rather than a single unit serving both roles.
