Additional Notes

The Chrysler Cordoba uses three distinct sealed beam headlight types across its 1975-1983 model years: H6024, H4651, H4656, and H6054. All four are ANSI-standardized units rated at 12V and are sold and used throughout the United States and Canada.
All headlight units fitted to the Cordoba across this production span are sealed beam assemblies, meaning the lens, reflector, and filament are fused into a single unit. When a filament fails, the entire assembly requires replacement rather than an individual bulb.
The H6024 is a 7-inch round sealed beam unit. It served as both the high beam and low beam headlight on the 1975-1977 Cordoba, with a single part number covering both functions in those years.
For the 1978-1979 model years, the Cordoba transitioned to 4x6-inch rectangular sealed beam units. The high beam position used the H4651, while the low beam position used the H4656. These two part numbers are not interchangeable despite sharing the same physical form factor.
The H6054 is a 5x7-inch rectangular sealed beam unit. It was fitted to the 1980-1983 Cordoba in both the high beam and low beam positions, making it the only headlight type on those vehicles where a single part number covers both functions.
The physical size difference between the H4651/H4656 units (4x6 inches) and the H6054 units (5x7 inches) means these rectangular types are not physically interchangeable with one another, even though both generations used rectangular housings.
The round H6024 units from the 1975-1977 years are dimensionally incompatible with either rectangular type used in later model years, as the housing shape and mounting configuration differ fundamentally.
The H4651 (high beam) and H4656 (low beam) share the same 4x6-inch rectangular form but carry separate ANSI designations because they contain different internal filament configurations suited to their respective beam functions.
