The Mercedes-Benz 250SL uses H6024 bulb size for both high beam and low beam headlight applications. The replacement chart covers 1966 to 1968 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 Mercedes-Benz 250SL uses the H6024 bulb type across all listed model years (1966-1968) for both high beam and low beam headlight positions.
The H6024 is an ANSI-standard sealed beam unit recognized in the United States and Canada, operating at 12 volts.
A sealed beam unit integrates the filament, reflector, and lens into a single non-serviceable assembly, meaning the entire unit requires replacement rather than an individual bulb.
The H6024 follows a 7-inch round form factor, a standardized size regulated under ANSI specifications for sealed beam headlights.
Because both the high beam and low beam positions share the H6024 specification on the 250SL, a single unit type serves both functions across the headlight system.
The sealed beam construction of the H6024 means it is not interchangeable with modern replaceable-bulb headlight assemblies, as the two designs represent fundamentally different fitment systems.
