The Volvo 142 uses H6024 bulb size for both high beam and low beam headlight applications. The replacement chart covers 1967 to 1974 production years with corresponding bulb size specifications.
The year-by-year compatibility chart below provides a quick reference to verify the correct bulb size for your vehicle.
The Volvo 142 uses the H6024 bulb type across all listed model years, 1967-1974, for both high beam and low beam headlight positions.
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 internal bulb.
The H6024 unit measures 7 inches in round format, a form factor that was widely standardized in North American automotive lighting regulations during this era.
The H6024 operates at 12 volts, consistent with the 12V electrical systems common to passenger vehicles of this period.
Because the Volvo 142 uses the same H6024 unit for both high beam and low beam functions, the sealed beam assembly serves a dual-filament role, with each filament dedicated to one lighting mode.
The H6024 designation follows ANSI standardization applicable to the United States and Canada, which means physically compatible sealed beam units from multiple manufacturers are generally interchangeable within that specification.
