Plymouth Arrow high beam and low beam headlight bulbs both use the H6024 size. The replacement chart covers 1976 to 1980 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 Plymouth Arrow uses the H6024 bulb size for both high beam and low beam headlights across all documented model years, 1976-1980.
The H6024 is a sealed beam unit, meaning the lens, reflector, and filament are fused into a single assembly. When the filament fails, the entire unit is replaced rather than an internal bulb.
The H6024 follows the ANSI standard format recognized in the United States and Canada, making it a standardized part rather than a proprietary one.
The unit is a 7-inch round sealed beam, a form factor that was common in North American vehicle regulations during the era when the Arrow was produced.
The H6024 operates at 12 volts, consistent with the standard electrical systems found in passenger vehicles of that period.
Because the Plymouth Arrow uses the same H6024 for both high and low beam positions, the vehicle does not use a dual-filament or separate-unit system for each function in the conventional sense; the H6024 itself contains dual filaments to serve both functions within one sealed assembly.
