Jeep Comanche high beam and low beam headlight bulbs both utilize the H6054 size. The replacement chart covers vehicle production spanning 1986 to 1992.
The year-by-year compatibility chart below provides a quick reference to verify the correct bulb size for your vehicle.
The Jeep Comanche uses the H6054 bulb size across all listed model years (1986-1992) for both high beam and low beam headlight positions.
The H6054 is an ANSI-standardized sealed beam unit recognized in both the United States and Canada, meaning it conforms to a regulated specification rather than a proprietary design.
The H6054 unit is a 5x7-inch rectangular sealed beam, which is a format in which the lens, reflector, and filament are fused into a single glass assembly rather than a housing that accepts a separate replaceable bulb.
Because the H6054 is a sealed beam unit, the entire assembly is replaced when the light fails, as opposed to only the bulb element inside.
The H6054 operates at 12 volts, which is consistent with standard automotive electrical systems.
The same H6054 unit serves both the high beam and low beam functions on the Jeep Comanche, indicating that the vehicle uses a dual-filament sealed beam design rather than separate single-filament units for each function.
The ANSI standardization of the H6054 means that units from different manufacturers sharing this designation are generally interchangeable, provided they conform to the same specification.
