The Mercedes-Benz 230 uses H6024 bulb size for both high beam and low beam headlight applications. The replacement chart covers vehicle production spanning 1966 to 1978 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 H6024 is the sole bulb type listed across all headlight positions in the Mercedes-Benz 230 specifications, appearing in both high beam and low beam applications for model years 1966-1969 and 1974-1978.
The H6024 is a 7-inch round sealed beam unit operating at 12 volts, conforming to ANSI standards applicable in the United States and Canada.
As a sealed beam unit, the H6024 integrates the filament, reflector, and lens into a single assembly. When the filament fails, the entire unit requires replacement rather than an internal bulb swap.
The H6024 serves both high beam and low beam functions in the Mercedes-Benz 230, meaning the same sealed beam unit is specified for each lighting position across all listed model years.
The 7-inch round form factor of the H6024 is a standardized size, which historically allowed interchangeability across many vehicle makes and models that adopted the same ANSI-regulated sealed beam format.
Because the H6024 is an ANSI-standardized sealed beam, aftermarket and OEM replacements from multiple manufacturers are generally produced to the same regulated specifications, provided the unit carries the correct H6024 designation.
