The Chevrolet B7 high beam and low beam headlight bulbs both utilize the H6054 size. The replacement chart covers vehicle production spanning 1993 to 2002.
The year-by-year compatibility chart below provides a quick reference to verify the correct bulb size for your vehicle.
The Chevrolet B7 uses the H6054 bulb size for both high beam and low beam headlights across all model years from 1993-2002.
The H6054 is an ANSI-standardized sealed beam unit recognized across the United States and Canada, meaning its physical and electrical specifications conform to a defined national standard rather than a proprietary manufacturer format.
The H6054 is a 5x7-inch rectangular sealed beam unit, a format in which the lens, reflector, and filament are fused into a single non-serviceable assembly.
Because the H6054 is a sealed beam unit, the entire assembly is replaced when the light fails, rather than a separate bulb element within a housing.
The H6054 operates at 12 volts, consistent with the standard electrical system voltage found in passenger vehicles of this type.
The identical H6054 fitment across both high beam and low beam positions on the Chevrolet B7 indicates the vehicle uses a dual-function or interchangeable sealed beam arrangement rather than separate dedicated housings 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 standard specifications.
