Toyota Starlet high beam and low beam headlight bulbs both use the H6054 size. The replacement chart covers 1981 to 1984 vehicle production years with corresponding bulb specifications.
The year-by-year compatibility chart below provides a quick reference to verify the correct bulb size for your vehicle.
The H6054 is an ANSI-standardized sealed beam unit used in the United States and Canada, operating at 12 volts in a 5x7-inch rectangular form factor.
Unlike bulb-based headlight systems, the H6054 is a sealed beam unit, meaning the lens, reflector, and filament are fused into a single assembly that is replaced as a whole when the filament fails.
The Toyota Starlet uses the H6054 for both high beam and low beam functions across all four model years listed (1981-1984), indicating that a single sealed beam unit serves both lighting roles.
Because the H6054 follows an ANSI standardized specification, units from different manufacturers are generally interchangeable as long as they conform to the same standard designation.
