Plymouth Champ high beam and low beam headlight bulbs both utilize the H6054 bulb size. The replacement chart covers vehicle production spanning 1979 to 1982.
The year-by-year compatibility chart below provides a quick reference to verify the correct bulb size for your vehicle.
The Plymouth Champ uses the H6054 bulb size across both the high beam and low beam headlight positions for the 1979-1982 model years.
The H6054 is an ANSI-standardized sealed beam unit recognized in both the United States and Canada, meaning the entire headlight assembly is replaced as a single unit rather than an internal bulb being swapped out.
The H6054 unit follows a 5x7-inch rectangular form factor, which is a regulated sealed beam format that allows for cross-brand fitment compatibility within that standardized size class.
The H6054 operates at 12 volts, consistent with the standard electrical systems found in passenger vehicles of that era.
Because the Plymouth Champ uses the same H6054 unit for both high and low beam functions, the vehicle relies on the dual-filament design built into the sealed beam itself to produce both lighting modes from a single housing per side.
The ANSI standardization of the H6054 means that replacement units from multiple manufacturers are generally interchangeable, provided they conform to the same 5x7-inch rectangular sealed beam specification.
