Subaru Standard high beam and low beam headlight bulbs both utilize the H6024 bulb size. The replacement chart covers vehicle production spanning 1979 to 1987.
The year-by-year compatibility chart below provides a quick reference to verify the correct bulb size for your vehicle.
The Subaru Standard uses the H6024 bulb type across both the high beam and low beam headlight positions for the 1979-1987 model years.
The H6024 is an ANSI-standardized sealed beam unit, meaning the lens, reflector, and filament are fused into a single non-serviceable assembly. When the filament fails, the entire unit is replaced rather than an individual bulb.
The H6024 unit is a 7-inch round format operating at 12 volts, conforming to a standardized size shared across many North American market vehicles of that era.
Because the H6024 serves both the high beam and low beam positions on the Subaru Standard, the same sealed beam unit is used in all four headlight sockets where applicable, simplifying parts sourcing.
The ANSI standardization of the H6024 means units from different manufacturers are dimensionally and electrically interchangeable, provided they carry the same designation.
The 12-volt rating of the H6024 corresponds to standard automotive electrical system voltage, making it directly compatible with the vehicle's charging and battery infrastructure without modification.
