The Mitsubishi Starion high beam and low beam headlight bulbs both utilize the H6054 size. The replacement chart covers vehicle production spanning 1983 to 1989.
The year-by-year compatibility chart below provides a quick reference to verify the correct bulb size for your vehicle.
The Mitsubishi Starion uses the H6054 bulb size across all model years from 1983-1989, covering both high beam and low beam headlight positions.
The H6054 is an ANSI-standardized sealed beam unit recognized across the United States and Canada, meaning the specification conforms to a regulated industry format rather than a proprietary design.
A sealed beam unit integrates the filament, reflector, and lens into a single fused assembly. When the filament fails, the entire unit requires replacement rather than an internal bulb swap.
The H6054 unit follows a 5x7-inch rectangular form factor, which is a common sealed beam profile shared across numerous vehicle applications of that era, contributing to broad parts availability.
The H6054 operates at 12 volts, consistent with the standard electrical system voltage found in passenger vehicles of this type.
Because the Mitsubishi Starion uses the same H6054 unit for both high and low beam functions, the headlight assembly relies on a dual-filament design within a single sealed beam rather than separate housings for each function.
The shared H6054 specification across all seven model years of the Starion indicates no headlight assembly changes were introduced between 1983 and 1989 that would affect bulb fitment.
